Hi everyone, first post here but been reading the forums for a while. Im a 3rd year EE student working on a small side project. My design requires a circuit to accept a $1 bill, validate it, and then perform an action. I have been looking at bill acceptors online and they all seem to have many inputs and outputs. I'm looking for an acceptor that basically has one output, signaling the successful acceptance of a $1 bill. I know this probably doesn't exist but I'm looking for someone to steer me in the right direction on what to buy and how I can make it do what it is I desire. Thanks in advance and sorry if this post wasn't in the proper forum, mods feel free to correct me on this.
