This very simple sketch scans the I2C-bus for devices. If a device is found, it is reported to the Arduino serial monitor.
This sketch is the first step to get the I2C communication working.
The sketch shows the 7-bit addresses of the found devices as hexadecimal values. That value can be used for the "Wire.begin" function which uses the 7-bit address. Some datasheets use the 8-bit address and some example sketches use decimal addresses.
This scanner supports I2C multiplexer and can be used for channel selection.
