The Crumble is an easy-to-use programmable controller which opens up great possibilities for ‘embedded intelligence’ as required by the National Curriculum. Non-electronics specialists can use it right away but it also offers unlimited potential for advanced users. You simply create a programme on a computer by moving icons into the right position – e.g., to turn things on and off – and then plug in the Crumble. The programme is immediately transferred and turns the Crumble into whatever you tell it to do. Drawing power from a very small battery, it might be applied to anything from turning LEDs on and off in smart clothing to driving and steering a robot. Software is free for PC, Mac and Linux (including the Raspberry Pi) and can be downloaded from Redfern Electronics.

The Crumble has been designed to encourage tinkering, using ‘croc leads’ for quick and simple connections. Pads allow terminal blocks to be fitted or a direct solder connection made, while the larger 4mm holes make an easy target for conductive thread and needle. It can drive two motors forwards and backwards at variable speeds. It has four IO (Input/Output) pads which allow connections to switches, LDRs, and full-colour LEDs, called Sparkles (32 are included).
