We finally received the coin acceptor today to profile the coins individually. The process of programming the coins was not hard at all, as the instructions were very clear. However, I could not get the data to be read on the serial monitor when connected to the LaunchPad. Another issue I had was that even before programming the coin acceptor, I did not know the proper wiring for it because it required 12 volts to power it, and a LaunchPad could only give 5 volts. I thought about the problem I was having, but then I remembered that I had a 12 volt battery holder for 8 AA batteries. I connected it to the coin acceptor, and sure enough, it powered on! To program it, I had 30 samples of each coin in order to get the most accurate readings. After it was successfully programmed, I tried putting foreign coins into it. I tried coins from UAE and UK, and they rejected those coins, so I am positive all the coins were profiled very well. Before moving on, I also have to adjust the coin counter box itself because it cannot house the coin acceptor as is. Tomorrow, I plan to use a jigsaw from the engineering room to create a spot for the coin acceptor!
