Hitachi’s HD44780 based 16×2 character LCD are very cheap and widely available, and is an essential part for any project that displays information. Using the LCD backpack, desired data can be ...

[Ricardo] has created an Arduino library to bring the QN8066 to the masses. The chip is rather easy to use – control is handled with a common I2C interface.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very ...

A header connects to an Arduino, which provides power and control over I2C. If you’re looking for an application, [Jason]’s prototype single-sideband radio shows the chip in action.
