    Correct, there are 2 kinds of 8 channel relays, active HIGH and active LOW. Just need to change code for this to the opposite values.

    Thats a lighter, i am releasing gas into the sensor.

    //#include <LiquidCrystal.h> //uncomment when not using I2C
    #include <LiquidCrystal_I2C.h>//uncomment when using a I2C

    Just remove the original liquid crystal code parts. and add this before void loop.

    //LiquidCrystal lcd(12, 11, 5, 4, 3, 2); //Uncomment when not using a I2C
    LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);// Uncomment when using a I2C
    //make sure you set the right adress. here are the most common ones.
    //PCF8574 = 0x20, PCF8574A = 0x38, PCF8574AT = 0x3F.

    Wire it up like this schematic on my blog: http://blog.arduinosensors.nl/2016/11/05/arduino-waterproof-thermistor-lcd1602a/
    So basically just add SCL on i2c to SCL on arduino, and SDA on i2c to SDA arduino, 5v to 5v and GND to GND. That should be it, and of course add this cd.begin(16,2); to the code in void loop, but it is already there so no need to do that,
    just remove the line #include <LiquidCrystal.h>
    and replace with #include <LiquidCrystal_I2C.h>

    then remove the line //LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
    and add LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
    Make sure to set right address for the i2c, in my case 0x27. Good luck.

  • Arduino - Home Control With Bluetooth And Voice about 5 years ago

    Ok, i am also a penetration tester once a while, i use kali linux, i only tested phones bluetooth.

  • Arduino - Home Control With Bluetooth And Voice about 5 years ago

    Hi Erick, your right the security of bluetooth is not really great. On the other hand this project is made for educational purpose, you could find a library for arduino for encryption, "AES" google that! To be honest i did not look into that yet. I just make fun starter projects.

  • Arduino - LCD 1602A Keypad LCD Shield Relay Control about 5 years ago

    Hi Rahul, You could solder some pins on the bottom of the arduino. Im not sure if you have a real one or a copy but i use copys from china and they have room to solder pins on the bottom of the arduino.

  • Arduino Arisoft Time Bomb Game over 5 years ago

    Hi, i am very sorry but i do not have the time to look into that right now. But it is possible to do that for sure. You can try to find someone else? A friend maybe. Because i got to much to do right now.

  • Arduino - Plant Watering System with TFT LCD over 5 years ago

    Hi, yes you can use the LCD on a uno as well. Succes with your project!
