I'm getting stuck in figuring out how to prototype this idea:
You pull a rope/string (like a pull-cord music-toy) and somehow arduino reads the number of rotations, and then rolls the rope back in = back the same number of rotations!
I tried using a small DC motor as sort of a rotary encoder, but haven't got far!
So... any advice (both soft/hardware concerned) would be much appreciated!
Hope it all sort of make sense?
