PiDojo – LCD Display

IMG_20151114_025717

Today we used a 20×4 Alphanumeric LCD Module to output information from our Raspberry Pi. These modules are cheap and easy to interface to the Raspberry Pi. We only need to use 8 pins on our Pi leaving loads of pins to connect input devices to.

We used Matt Hawkins’ LCD Test script to test our displays. Then we imported some code from that script to write some jokes to our displays. We will finish off these next week and we will start working on code for an ultrasonic distance sensor.

You can view our code on Dropbox and here are my slides from this week LCD_Display
