Coding with Crumbles

Year 5 children have been learning how to code 'crumbles'.  
The crumble is an electronic board which you can attach up to two motors, lights, buzzers etc and attach lots of switches and sensors to control how they operate. It plugs into your pc via usb and you can program it via the free drag and drop crumble software. Motors and buzzers are powered by 4.5v-5v battery packs
Year 5 children recently completed a project where they had to create a traffic light sequence using LED's.  
It was a challenging project which required them to think carefully about the sequence of lights and time the LED's.  
They also created LED light sequences that required If and Else statements and controlled a light sensor.
