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!
If you thought the tiny, convenient 8-pin PICAXE-08M was handy, imaging combining it into a board with the really handy L293D motor driver IC.. This is about as simple as a board can get to let you conveniently drive 4 outputs from a PICAXE.
But keep in mind that this is a simple board, and you are restricted to running it at a maximum of 6V, so that means your motor (or other loads) should not total more than 800mA at 4.5V (the L293D "eats" 1.5V).
