Raspberry Pi I2C LCD Set Up and Programming
In this video Circuit Basics show us how to use I2C to connect an LCD to the Raspberry Pi. After showing you how to connect the LCD to the Pi with a PCF8574 (http://www.circuitbasics.com/pj6v), they show you how to program it. First I'll cover the basic stuff like printing text to the...
