About Simple pin control over I2C using the python smbus2 library for Raspberry Pi and the Wire library for Arduino.

In this project, arduino is connected to LCD and Keypad with only two pin using I2C communication This project requires you to have proteus simulation software to simmulate the circuit and arduino IDE ...

My first thought was to use an Arduino Nano to test the sensor module through a special Nano I 2 C shield lying around. But later I decided to try the Seeeduino Nano as it provides a dedicated I 2 C ...
