Without going into too much depth of my project, I will need to measure a how close my hand is to the ground and hopefully get an analog reading from that. I need them to work in a poorly lit area and I have the liberty to mount them on the ceiling or floor or both.
Is there anything out there that can do this?
I am placing a Sparkfun order soon with other stuff I need. If it can be bought there, it would be best.
