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 ...

🔍 Universal port and I2C device scanner for Arduino, ESP32, and ESP8266 microcontrollers. Automatically detects active ports, connected sensors, and I2C devices with automatic identification. Arduino ...

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 ...

A tiny I2C-bus scanner with a nice tiny graphic OLED display and an AVR ATtiny44. This scanner displays the addresses of all attached I2C devices in a small matrix. The value is shiftet one bit to the ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
