hi all, i'v designed a 8x8 matrix which is controlled by a 16f876a displaying the the time from a ds1337 ic.The problem is i only want the display to turn on and display the time when some one is standing in front of it and if possible i want to be able to adjust the distance that turns it on. I have no idea on how to do any motion detection, should i be using i.r emitters and reciever or something else.
please can some one help me with the circuit and ill try and do the code for it.
many thanks
jason
