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, ...

This article shows how to use an Arduino Uno/Nano microcontroller with an OLED display module ... it’d be better to use a pre-wired MAX6675 breakout board rather than a bare chip soldered on an SMD ...

Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will record what is going on for a set time interval, then dump the data via serial as a .csv.
