For several microcontroller projects, the integration of a minuscule display panel can be handy to show relevant information. For example, information gathered by an external sensor module. Here we ...

A tiny I2C-bus scanner with a nice tiny graphic OLED display and an AVR ATtiny44. This scanner displays the addresses of all attached I2C devices in a small matrix. The value is shiftet one bit to the ...

The venerable I²C bus has never been more popular. Most modern microcontrollers either have a hardware I²C interface or are capable of bit-banging one in software. Many sensors, AD and DA converters, ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

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, ...

Anyone who follows my articles here at TweakTown knows that I am a sucker for new Arduino-compatible development kits, and I especially like the micro-sized boards that are easily hidden inside ...
