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 ...

This very simple sketch scans the I 2 C-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 I 2 C communication working. The ...

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 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, ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
