could anyone here help me in making a wheel encoder using optical sensor? i saw something in the net that uses a disc with black and white lines as markers of each step. what do i need to count the number of turns of the wheel? how do you do it?
Could you elaborate more on whether you want an incremental encoder, absolute encoder or multi-turn absolute encoder? Also, what is the resolution that you require? The optical pattern, sensors and controllers depend on the above requirements.
