    I used a simple 9v battery with a DC barrel plug

    Nice job on this project.

  • Virtual Arduino Tennis 5 months ago

    Yes. My led strip isn't from adafruit either. And you can use any backing you want for the board. I used poster board for mine.

  • Virtual Arduino Tennis 6 months ago

    The board can be any size you want. It's just the matrix that has to be 15 LEDs wide and 10 LEDs tall.

  • How to Make a NeoPixel Matrix 6 months ago

    I replied to your other comment on the Matrix Tennis project

  • Virtual Arduino Tennis 6 months ago

    I have already made the matrix, so I don't have any more LED strips to cut. The code works with a matrix that is 15 LEDs wide and 10 LEDs tall. Just buy a 150 LED strip from Amazon.com and make sure that it has 30 LEDs per meter, and is 5 meters long. If you look in the "How to make a neopixel matrix" project you will see that I cut the strips at 10 LED intervals, which makes 15 strips that are 10 LEDs long. Take note of the arrows on the strips, as they will alternate on each column. Just solder wires between the strips as seen in the guides pictures. 5v -> 5v, GND -> GND, and DO -> DI. Just make sure there aren't and short circuits, as that will ruin the Arduino board and/or the matrix.

    I use enthought canopy with Python 2.7 for running .py files.

    Thanks for using my project as inspiration for your own project! Here is an explanation:

    You can't even run Python on an Arduino normally. Arduinos run compiled C++ code. The Python script runs off of a PC or laptop that has Bluetooth and an open USB port. You use the HC-05 on the racket to connect via Bluetooth. Then you connect the matrix to an Arduino Nano and that connects to the USB port on the same computer. Make sure the COM ports are correct as well.

    If you need any more help just reply to this message or message me. :-)

  • 3D Room Visualizer 6 months ago

    It should show the image after all of the values are taken, which will take about 5-10 min. The "img.show()" at the bottom the the script will show the image.

    Thanks! I enjoyed making this. It's good that you're teaching your kids programming as it's a very important skill to have.

    The Arduino Uno is an AVR board

    What do you mean by this?

  • Motion Controlled Color Changer! 9 months ago

    Ok, thanks for asking

  • Motion Controlled Color Changer! 9 months ago

    You're welcome! Hope you get it worked out! :-D

  • Motion Controlled Color Changer! 9 months ago

    Maybe run the APDS-9960 library example (gesture interrupt) by itself and then try my code again.

  • Motion Controlled Color Changer! 9 months ago

    Only moving your hand left or right over it will change the LED colors.

  • Motion Controlled Color Changer! 9 months ago

    Have you moved in other directions? Maybe tape the sensor facing upwards and then try it.

  • Motion Controlled Color Changer! 9 months ago

    and try to put your hand 5 inches away and move about 8 inches over the sensor

  • Motion Controlled Color Changer! 9 months ago

    do you have enough light above your hand?

  • Motion Controlled Color Changer! 9 months ago

    For the "up", are you swiping your hand across or away from the sensor?

  • Motion Controlled Color Changer! 9 months ago

    Copy and paste what you are seeing in the Serial monitor.

  • Arduino LCD Thermostat 10 months ago

    Just install the dht library by going to sketch: libraries: manage libraries: search "dht" install it, then recompile!

  • Arduino LCD Thermostat 12 months ago

    hmmmm... Check the wiring.

  • Arduino LCD Thermostat 12 months ago

    you can adapt the code to Celsius by going to lines 18 and 27, then change "float f = dht.readTemperature(true);" to: "float f = dht.readTemperature();"

  • Arduino LCD Thermostat 12 months ago

    just go into the Arduino IDE, then include library, manage libraries, search for: "DHT", click on it, click install. That's it!

  • Arduino LCD Thermostat about 1 year ago

    I think it's great that you're taking an interest in MCUs! The Arduino doesn't go into sleep mode when a delay is active. A delay simply paused the progression of the code for a set amount of milliseconds. An OLED display is more complicated than an LCD, but you can find Sparkfun OLED displays that use I2C and libraries. Have fun! :)

  • Arduino Humidifier Control about 1 year ago

    What you do is: Open Arduino IDE, go to "sketch" -> "Include libraries" -> "manage libraries" -> then look up: "DHT" -> Install the "DHT sensor library by adafruit - version 1.2.2", then re-run your sketch.

  • Arduino Humidifier Control about 1 year ago

    It should be fixed now. I had to change 3 areas of the code. Works for me now :). Reply if you have any further issues.

  • DIY Flight Instruments for Horizon and Compass over 1 year ago

    That would be cool! Maybe a 2.7 inch touch screen I2C OLED with a nano? Just some ideas :)

  • Ultrasonic Map-Maker using an Arduino Yun over 1 year ago

    ok, sorry for the foolish comment. I will delete now. Thanks

  • Ultrasonic Map-Maker using an Arduino Yun over 1 year ago

    OK, sorry if I came across too harshly. Thanks for crediting me with the design and happy making! Thanks again!

  • Bluetooth Controlled Light Switch over 1 year ago

    You could also remove most of your loop code and instead use a function. Doing: "turn(<state>,<flag>)" and make that control the motor. Clean code is the best code!

  • Bluetooth Controlled Light Switch over 1 year ago

    What about making it relay controlled? Just wire the light to a 5v logic relay and make it controlled through BLE or through an internet portal via an esp8266. Otherwise great concept!

  • 3D Room Visualizer over 1 year ago

    Any 5v arduino board will work, so yes, you can use the nano. On your pc the python script will execute and once finished it will show a .jpg image. The image looks like a heatmap but instead each pixel correlates with the distance. The image is 100 x 100 pixels large.

  • YAHOO! Stock Ticker over 1 year ago

    Nope! Everything stays the same! This code works on all 5v Arduino boards.

  • 3D Room Visualizer over 1 year ago

    It does take a minute to scan, as it has to scan each pixel individually for 100x 100 pixels, so moving object detection is harder. But you can visualize the position of an object if it can stay still for about 5 minutes at a time.

  • 3D Room Visualizer over 1 year ago

    If you are needing to show a room and how it looks, detecting objects, etc. Thanks for the encouragement BTW!

  • 3D Room Visualizer over 1 year ago

    Sadly, it is only a 2d scan. it creates a .png or .jpg that is 100 x 100 px . Imagine a thermal imaging camera, this measures distance instead.

    I'm so lonely ;-;

  • 3D Room Visualizer over 1 year ago

    Glad you asked! My next project will be coming out soon.

  • 3D Room Visualizer over 1 year ago

    Amazing project. Please do more.

  • Solar Power Desalination Facility over 1 year ago

    Agreed

  • Measure your reaction time over 1 year ago

    You can't react! You will have to pay the fine bros a fine. They trademarked any reaction online. #unsubthefinebros

  • Arduino Controlled Pinball Machine over 1 year ago

    This is so cool!

  • 5vCircuitPowerMeter over 1 year ago

    yeah, you are very correct. the arduino can't accurately control the current through its pins when there is a load.

  • Ball Tracking Robot over 1 year ago

    yeah that guy is stupid

    Roses are red, violets are blue, the title's in English, the article should be too.

    Nothing about it!? Really!? Wow, please just add something about how you made this or what it does.
