Looking for a more flexibility out of your Sumovore, but you're not too up on programming? The PICAXE is a PIC-based solution, programmable with flowcharts - and we've added it to the Sumovore!
The PICAXE-20M Project Board Kit lets you quickly develop your project, and drive it with the PICAXE-20M IC!
If you thought the PICAXE was a handy chip on it's own, try it with a bundled L293D motor driver chip! This will let you make very small and tidy motorized projects with the simplicity of the PICAXE development system!
