    Hi, if you need anything you can email me through Hackster (I think you did that). In relation to the WiFi alerts, in this case you could only tell if no data was sent by the device for a period of time. As in if the device was set to send data at intervals of 10 mins and 20 mins pass without data, then the device is either dead or disconnected (the voltage can be checked to rule the first out).

    Hi, the Arduino Uno WiFi does not work with GSM but with WiFi so you will not need a SIM card. The basis for the code is the same, the only difference is the code for connecting to the backend. You can check out examples provided (uses the same wifi chip as MKR 1000 so if you can find a tutorial for connecting the MKR 1000 to IoT Hub, you should be able to easily adapt the code).

    Hi, sorry for not replying (Hackster doesn't send emails for comments).
    Yes, the project is doable with an Arduino Uno but you will need a method of sending the data to the backend. I would recommend using a Wifi module or a GSM module for that (make sure you get one with plenty of documentation and examples to get you going).
    Try out the Arduino Uno Wifi (may be a bit cheaper than MKR GSM). Get back to me if you need further assistance

    Sorry for the delayed response,
    The dimensions (if printing the cylindrical enclosure I used) would be a height of 65mm and a radius of 65mm. The enclosure is elevated at 100mm above the ground. If you need any further assistance or the CAD file, feel free to email me.

    Update 1.1
    After getting many requests to use an ESP8266 module instead of a Yún, I have a code draft done for an Arduino 5v board with an ESP8266 module, this code can be found at this link https://create.arduino.cc/editor/LightPro/65a1ee15-d56b-410c-933d-4e943895d320.

    I am S-o sorry for the 2 month delay. This is probably irrelevant to you now but I don’t have an autonomous cleaning system in mind. The design requires manual cleaning.

    Update 1.1

    Hi Everyone,
    I just wanted to let you know that I updated the project so that the device sends the battery voltage to the cloud. Now the battery level can be visualised in Lagoon. To access the variable in Lagoon, search for batteryVoltage.

    The corrosion of the moisture sensor is definitely an issue. The corrosion cannot be stopped but there are a few ways to slow it down. If you would connect the VIN pin of the module to a digital pin on the Arduino and only power the device when taking readings, the lifespan of the device will increase. The sensors will have to be replaced from time to time.

    I have been planning to do something similar using a Particle Mesh network. Collecting the data and then controlling irrigation.

    Hi there,
    I have tested it with the power bank and mine does not turn off when the device goes into low-power mode. Though I tested my power bank with the MKR GSM taking samples at intervals of 10 seconds, so that is not a long time sleeping, I have not tested the power bank with the device going to sleep for longer.

    The Li-Po works great though, the device can run a couple of days off a Li-Po battery so that would be the preferred option.
    Andrei.

  • SmartAgro about 2 years ago

    Thank you,
    I would have originally used SigFox on the device but you are restricted to payloads of 12 bytes so I could not fit all the data in that package. Other wireless technologies could also be used. Thinking of 2 devices communicating through RF, one of the devices measuring parameters while the other acting like a gateway between it and the backend.
    Looking forward to seeing your project,
    Andrei.

  • SmartAgro about 2 years ago

    Hi there,
    Yes I am aware of that, for the purpose of this prototype, I have decided to use this board as it is easy to prototype with. Other “low cost” alternatives are available and can be implemented.

  • PhoneLocator over 2 years ago

    For the phone to "snap" a picture using its onboard cameras, you will need a local app to run on it. The app will have to somehow detect the signal sent by the other device that is searching for it, this can be done through an SMS message or a web hook, then take the pictures and either send them back to the device or upload them to a cloud, which again requires Wi-Fi.
    Andrei.

  • PhoneLocator over 2 years ago

    Hi there,
    like in all other phone locating services, like Find My iPhone, Wi-Fi is required to get the location of the mobile device, as the phone has to send the location data to the device requiring it.

    "Flashing the phone"? The Blynk app must run in the background for the project to work.

  • TFT Graphing: Live History Graphs over 2 years ago

    Thank you, great, that solved the issue, now the value in the corner will not appear anymore.
    I only got a chance to run it now, 17 days later, but it worked.
    Thanks again

  • TFT Graphing: Live History Graphs over 2 years ago

    Ok, that is great, thank you.
    I will sort the code out over the weekend,
    Andrei.

  • TFT Graphing: Live History Graphs over 2 years ago

    Hi there,
    Great that it suits you, the Elegoo library is branched off the Adafruit library so they should be nearly identical. The issue that you have pointed out does not have to do with the library, nor is it a bug in the code.

    I have not mentioned this in the tutorial but if you can find where the variables valueBlock, timeBlock and locationBlock are defined, you will see that they are buffers with an index of 100 each, the device will crash after 100 runs, to prevent that change the index to a higher number, 1000?

    Let me know if it works for you.
    Andrei.

  • TFT Graphing: Live History Graphs over 2 years ago

    hi there,
    the number in the corner seems to be a bug that pops up occasionally, I will be working on fixing it, while I do that, try drawing a white rectangle in the corner after every plot, this should fix the issue.

  • MyRiver over 2 years ago

    Hi there, sorry for the late reply, the contest is over and I can now edit the publication. Thank you for the feedback, it is always good to have feedback from experienced people.
    Why the LED and Photoresistor, well I initially wanted to use a turbidity sensor and ordered it but the sensor did not arrive in time and so I had to come up with another solution.
    The final project does have a turbidity sensor though and there is no need to edit the Arduino code to replace the photoresistor with the turbidity sensor (well just take out the LED write).
    Thank you

  • Miniature RoboticArm almost 3 years ago

    Hi there,
    If you wish to add schematics in image format, you can take a screenshot of your Fritzing window and then when you add the schematics to Hackster, select the “add image” button and that will add the image to the schematics,
    Also, if you forgot to add something to your docs, you can edit the publication at any time by going into your project and clicking the edit button at the top of the window.

  • SmartPostBox almost 3 years ago

    Hi there, 
    Unfortunately you would need multiple devices to do that, as the MKR Fox does not set the email it sends the mail to locally, it is done in the backend,
    One option would be to send the user’s email in the body of the SigFox message but the user’s email may be longer than 12 bytes, so that will not work.
    The best way is to make separate mailboxes, and configure the backend different for them all.
    If you need any further help with the project, feel free to contact me at lightpro64@gmail.com.
    Andrei.

  • SmartPostBox almost 3 years ago

    Hi there,
    Sorry for the delayed response, I have mentioned above that you can use LoRaWAN as an alternative to SigFox, I would recommend using the Arduino MKR WAN if you want to implement LoRa.
    I have attached some useful info and links about adapting the code to LoRaWAN in the response above.
    Andrei.

  • PhoneLocator almost 3 years ago

    Hi, the link in the image with the email of the project is precise to around 10km, so if you search for the location on google maps, you will get something just off the Irish Sea (I don't give my location away that easily).

  • Turn Lights On When Approaching Home almost 3 years ago

    ok,
    So are you thinking of making the location of home variable, so for example setting the location of your car in motion as home.
    If so, this could be done with a GPS module connected to the Arduino Yun, it updates the location of home at an interval of time, and if the location of the phone is close to the updated location, the user is noted as "at home".
    It is a great idea, if you need any further help, feel free to email me at lightpro64@gmail.com.
    Andrei

  • PhoneLocator almost 3 years ago

    sure, my email is lightpro64@gmail.com, feel free to ask me anything you want.

  • PhoneLocator almost 3 years ago

    Yes,
    You can use the Arduino Uno in two ways.

    1. You can attach a WiFi or Ethernet module or shield to the Arduino Uno and edit the sketch to interface the new device, if you are going ahead with this way, there is a Blynk example that can help you with changing the code https://examples.blynk.cc/?board=Arduino%20Uno&shield=Ethernet%20Shield%20W5100&example=GettingStarted%2FBlynkBlink, you can select the shield or module you are using in the browser, feel free to email me if you need any more help with adapting the code, I may be able to write a version for you.

    2. You can use the Arduino Uno alone, just connect it to your Mac/PC and use its WiFi capabilities, you can adapt the code using the fallowing link https://examples.blynk.cc/?board=Arduino%20Uno&shield=Serial%20or%20USB&example=GettingStarted%2FBlynkBlink. There is also a great video for doing this on a Mac, https://www.youtube.com/watch?v=fgzvoan_3_w&t=319s. If you are using a Mac, you can email me if you need any help with setting up the connection to the computer or if you need any help with the code.

    Andrei.

  • SmartPostBox almost 3 years ago

    Sure,
    you can use LoRaWAN for the project, you will just need to adapt the code to send the message using LoRa and not SigFox, if you are intending to use the Arduino Mkr WAN, you can refer to this link for help with the LoRa library functions https://www.arduino.cc/en/Reference/MKRWAN, I have to admit that I don’t have much experience with LoRa so I cannot give you a step by step guide into editing the code.
    If you want to use a LoRa WAN module, I am sure that there would be libraries available to interface it, but I would suggest using the Arduino Mkr WAN as you will be able to adapt the code easier.

    You will also have to change some stuff on Wia, Wia has a great tutorial for connecting a LoRaWAN device to the platform here https://www.hackster.io/Spivey/connecting-a-lora-device-to-wia-via-the-things-network-560bc6, if you need any additional help on the Wia side of things, be sure to ask them for help, they have great customer support.

    I have never worked with weightless before, so I am not sure if it will work using an Arduino device, but you can try it out.

    Good Luck with the project.

  • TFT Graphing: Live History Graphs almost 3 years ago

    Hi,
    Sorry for that, I have accidentally labeled it wrong,
    I have fixed the problem with the sketch.

  • TFT Graphing: Bar Charts almost 3 years ago

    No problem,
    I am currently working on an area graph, it should be done by the middle of August.

  • SmartPostBox almost 3 years ago

    Would you have a link to the documentation of the project or any guide on building it,
    thanks

  • SmartPostBox almost 3 years ago

    Great,
    I heard that you are using WiFi, would the project work if the post box was a larger distance from the house?
    Would the device know if mail was actually placed in the mail box or will it only look for the door opening?

  • SmartPostBox almost 3 years ago

    I am not sure on the exact time that it can stay in the post box without replacing batteries, I do not conduct extensive tests on the battery life of the product, though I am aware that the project can survive on 2 AA batteries over 1 day.

    Though there is a very simple and effective way to reduce the consumption, if you replace the line of code that sets the laser pin high with an analogWrite() function, and set the value to around 600, then set the threshold in the condition that checks if the light level is below the light level to a lower number, so like

    change if(lightIntensity < 800) to if(lightIntensity < 500)

    (note that I have not tested the method above but it should work well)
    Play around with the value until it works best.
    Good luck.

  • TFT Graphing: Live History Graphs almost 3 years ago

    Hi there,
    You need to download and install the Elegoo Libraries for the TFT LCD, if you purchased the Elegoo TFT LCD, you would find the libraries on the CD received.
    You can fallow the guide here for installing additional libraries https://www.arduino.cc/en/guide/libraries.

  • TFT Graphing: Live History Graphs about 3 years ago

    Thank you,
    you can email me if you need any help with integrating the graph in your project.

  • Turn Lights On When Approaching Home about 3 years ago

    It is not necessary to use the Yun, you could use any Arduino board that uses WiFi and is supported by the Blynk library, like the MKR1000, WiFi shield. There may be others supported, you could also use an esp device. The code will be subject to minor modification if you change the board though, refer to examples.blynk.cc for guidence on editing the code, email me if you need any help modifying the code.

  • Turn Lights On When Approaching Home about 3 years ago

    Hello,
    Yes, that might be an issue over time, I am not really concentrated on battery usage in this project but there are some small things that might help your battery life;
    - I would put a delay at the end of the void loop, this will make the Arduino request the data from Blynk at larger intervals of time, which means that Blynk does not need to read and send your phone's location continuously, which may save some battery life.
    - You could also set the precision of the GPS widget to a larger area, eg 100m, this will make your phone send less data over WiFi/mobile data, which may also save some battery life, though minimal.

    I am not sure by how much these solutions would save up, but you could give it a try.
    Good Luck,
    Andrei Florian

  • Turn Lights On When Approaching Home about 3 years ago

    Its great that it works,

    proDebug is a setup that is included in most of my public projects, if it is enabled (set to 1) the Arduino will print to the serial monitor, and it requires the serial monitor open for the project to work, if it is off (set to 0), it will not need the serial monitor and is ideal to use on the field.

    In the current code, the Arduino will receive the location constantly, so it basically depends on the speed of your WiFi/Mobile data, there is about 50 milliseconds of a delay between receiving the location from Blynk, if you would like to not waste a lot of your mobile data, you can place a delay of about 5 seconds at the end of the void loop.

    The delays in the setup loop are not necessary, I put them there to smooth the Serial Prints as I am not a fan of the Arduino printing tonnes of data to the Serial Monitor Constantly, you can take them out if you wish so.

    GPS is not extremely precise, if you down the size to +/-0.00001, your phone may be slightly offset from its initial location (set as myLocation in the code) (it's enough to be in another room) and it will be considered outside home because the box around home will be too small at that size, I would recommend +/- 0.001, so that the light will turn on when you are on your home's street.

    Andrei.

  • Turn Lights On When Approaching Home about 3 years ago

    Thank you Jon,
    Looks like I have copied the code incorrectly from my desktop IDE, I have just updated the code to include your suggestion for the if loop.
    Regarding the longitude, there should not be an issue as I have tested multiple co-ordinates successfully.
    I am very sorry for any inconvenience caused.
    Andrei

  • Turn Lights On When Approaching Home about 3 years ago

    Hello,
    the project does work with a 220Ω resistor, and that is the value I have utilised,
    Hackster does not have a 220Ω resistor pack, but it has a 221Ω one. You will find a detailed list of materials in the Required Apparatus section in Constructing The Project.

  • Turn Lights On When Approaching Home about 3 years ago

    Hello,
    I forgot about closing the door, you could indeed use an ultrasonic sensor placed just outside the garage door, when you are close to the garage, the door opens, then you could read the ultrasonic sensor value and wait until it detects the car, then the Arduino can wait until the value goes back to normal and then the door could close.
    Please notify me if you need any help with the code.

  • Turn Lights On When Approaching Home about 3 years ago

    Hello,
    Yes this poject would be suited to open a garage door. As I do not personally have a garage, I am not sure how the door is operated, but if you could use a relay, the code can stay the same. Feel free to reply if you need any additional help.

  • Turn Lights On When Approaching Home about 3 years ago

    Hello there, thank you, this project could be made with an ESP8266, though you will need to adapt your code to the board, you could also use the Arduino Uno provided you connect an external WiFi module or a WiFi shield, the ESP8266 could be a better option, here is the code adapted for the ESP8266, note that I have not tested it, so test it out to make sure it works, here is the link to the code https://create.arduino.cc/editor/LightPro/65a1ee15-d56b-410c-933d-4e943895d320, insert your WiFi SSID and Password and you should be good to go. Wire the LED to a pin and make sure to set the pin in the code to the pin you have connected the LED to. Good Luck.

  • Back Up SD File to Dropbox about 3 years ago

    Thank you, to be sure that the project works, it is ideal to use an SD card with a capacity of up to 32GB, so you can use an 8GB (or smaller), 16GB or 32GB SD card. I have tested an 8GB and 16GB SD card and It worked well. If you have an SD card with a larger volume hanging around, you could test it out.

  • Back Up SD File to Dropbox about 3 years ago

    It will work with the Arduino Uno provided you attach a Yún shield to it. You will also need an SD card module. If you decide to go ahead with this option, feel free to contact me at lightpro64@gmail.com if you need help with the code alteration.

  • Back Up SD File to Dropbox about 3 years ago

    Thank You, I really appreciate it.

  • RFID Dropbox Logger over 3 years ago

    Thank you, I am sorry that the project does not meet your requirements. I have created a sketch that might meet your needs, a single Arduino Yún is connected to 3 different feeds on Adafruit IO, when a certain card is detected, the Yun will trigger the function for the employee owning the card. So when a card is scanned; the Arduino will read its ID and post the data to the correct feed. There are 3 APIs running on IFTTT watching each one of the feeds. All the APIs will write to the same Dropbox document. So you will get a response like this in Dropbox:

    March 2, 2018 at 12:03PM - Alex Scanned Card
    March 2, 2018 at 12:18PM - Emma Scanned Card

    You can set this project to your requirements, you can add as many employee's as you want, there is an instructions file attached to the code which will guide you through the setup project.

    Here is the Project
    https://create.arduino.cc/editor/LightPro/dd16f6db-baec-4a0c-a2ce-1feb0752136b

    If you have any problems, feel free to email me at lightpro64@gmail.com

  • SmartWay over 3 years ago

    I am sorry to hear that,
    There are a few things to check:

    • Ensure that your GPS module is functional
    • Ensure that the GPS library functions with the certain module (upload a test example)
    • Disconnect the GPS module while uploading the code
    • Ensure that you have a SigFox account and your device is registered
    • Ensure that the wiring is correct
    • Ensure that all variables marked TODO have been edited
    • Ensure that you replaced the values in the main if loops with your values

    If you are wondering how to do the last step; go to google maps and get the co-ordinates of the four vertices of a square surrounding the school, home and restriction area of the child's route.
    For any more queries, feel free to email me at lightpro64@gmail.com.

  • SmartWay over 3 years ago

    No, sorry, the project can only work with the MKR 1200 Fox because a SigFox connection is needed for the project, which the Uno does not provide.
