Hi All.
Is anyone interested in coming to UCC to design a Note reader for
dispense, I have a few ideas in mind on how to do it but require some
assistance.
Anyone Keen for later today or tonight?
Idea:
Grid of 6~ LDR's with white light on base projecting thru note,
Depending on the amount of light received on the flip side determines
what note it is, Its Sorta foolproof as Plastic/Paper will allow
more/less light through. And a small motor to pull the note in/out,
PIC or AVR to check the light levels of each LDR.
Pretty simple really...
