Two ready-to-upload Arduino sketches for finding the addresses of I2C devices on your bus. Stop guessing addresses and stop digging through datasheets — scan the bus directly and get the answer in ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

This project demonstrates how to scan and detect I²C devices connected to an ESP32 using the Arduino framework in PlatformIO. The program checks all possible I²C addresses and prints the addresses of ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
