  1. Raspberry Pi with Pibrella

  2. Objectives Sequence instructions Use selection (if, then, else) Use repetition Make lights flash and buzzers sound Push the big red button!

  3. Getting started We're going to be using Scratch to program the Pibrella Firstly, we need to start the GPIO (General Purpose Input Output) Server We'll then turn on the red light These commands are case sensitive, so check you use of lower and upper case (capital) letters carefully

  4. Challenges - Lights Program a key to turn the red light off Program a key make the red light flash Program a key to make the yellow light flash Program a key to make the green light flash Program a key to turn all lights off! Program a key to make the traffic light sequence
