Показать описание
This is a homemade 4-bit gray code rotary encoder.
Encoder design was made on Inkscape and milled in my homemade CNC.
I used a simple circuit with IR LEDs, photo transistors and resistors connected on Arduino Leonardo board.

Already some time since diffusion, as I was looking for DIY gray encoder, thanks for sharing.
Looks like you have made a "reverse" encoder (1st bit in the center and last bit on the exterior ), but the principle is mastered : nice.
I really enjoy your diagram it give me some ideas.
Thanks from France!
