Dr. Monk’s DIY Electronics Blog: LED Clock using Raspberry Pi. Simon writes -
Okay, so if you were going to make a simple LED 4 digit clock, you probably wouldn’t start with a Raspberry Pi. But I wanted to test out I2C on the Pi and Adafruit’s I2C LED displays looked like a good bet. I also used a level converter to convert the Pi’s 3.3V I2C to the 5V I2C required by the LED module.
