Here is an instruction to figure out the I2C address ofthe device installed on the Maqueen platform.


Hardware:

-I2C device (sensors, LCD,etc.)  
-4 pin jump wire

Software:

4. After addingboth, you will find the blocks in the programming page. And then program likethis and it will display the all detected I2Caddresses in the serial monitor.

5. set upyour connection, connect the micro bit with PC and plug the micro bit on the Maqueenchassis. And connect the I2C module to I2C port.

DifferentI2C modules have different I2C addresses. (We are using BME 280 Environmentsensor and Li-battery fuel gauge as examples here)

6. Uploadthe code and open the Serial. If you plug nothing, the detected I2C address isonly 0x10. Then plug BME280 Environment sensor, it gives one more I2C address,which is
0x36. Then switch to the fuel gauge module, the I2C address changes to 0x77.

That is how I determine the I2C address of a deviceinstalled on Maqueen. Hope it can be helpful for you.
