i dont know where i can start with my problem. What do i want to do?
I want to detect the moving of an band of Metal or plastik. I thought about some mechanic things, but for my projekt i need some exact value like an lasermouse sensor or so.
I thought about "rotary decoding" like an old mousewheel or so. There i´ve got the precission problems and i can not detect an minimal moving of the strip.
I found something on the internet by Sparkfun.touch this
So this works for one band i think, but i need it 32 times and i have to recognize every single moving. So that i know which band moves forward or backwards. I thought about something like an BUS-system, so that everysensor got his own ID an sends an String to the mainboard.
So at all, is it possible to wire 32 of the sparkfun-device and recognize every single position with a sort of an BUS system?
I want to use an Arduino Mega to get all these things connected and to interpret it.
Sorry for my bad english.
I´m glad to hear from anyone an hint or an solution.
