robodatech.Find I2C device addresses for sensors, displays, and expanders.
Open in compiler →Source code and build tools are available in the protected platform workspace.
How it works
Discover I2C addresses on the board SDA/SCL bus.
- Wire SDA and SCL using the board-specific map.
- Share GND between all I2C devices.
- Run the scanner and open Serial Monitor.
- Use the printed address in later sensor/display sketches.
