The Crumble is a programmable controller that can be coded to drive outputs such as motors and lights known as sparkles. It uses crocodile leads for simple connections and once programmed it can be easily embedded into a design or product.

All the Crumble software is available for free to download from redfern.co.uk.
The 'getting started guide' available from the Redfern website is an excellent starting point for those that haven't used Crumble before or need a refresher!
