We have started our new physical computing unit by beginning to explore the concept of selection in programming using the Crumble programming environment. We have been learning how to control the Sparkle unit using the Crumble and we’ve managed to make LEDs turn on, flash, change colour and also use loops and infinite loops. It was rather like being in a disco in the class yesterday afternoon; all that was missing was the DJ Express! We’ve had an awful lot of fun and shown a lot of resilience with trying to get our coding correct by designing correct sequences of actions for the components. If we don’t get it right, it doesn’t light up!
