An Ultimaker 3D Printer Connected to an Adafruit Coin Acceptor

Charlotte Jansen connected the Adafruit Coin Acceptor to an Ultimaker 3D Printer with an Arduino.

Your project may be free-as-in-speech, but that doesn’t mean it has to be free-as-in-beer. This handy coin validator/acceptor module is just like the ones you’ve seen in arcades. First, program it with what coin you want it to accept, any coin from 10.8mm to 25.1mm in diameter can be used so you can use American, European, Japanese, Canadian, etc. coins as long as they fit. When a valid coin is inserted, the output line will pulse for 20-60ms (configurable). The acceptor looks for diameter, thickness, dropping speed, etc to determine if a coin is valid. You can also select 3 different “strictness” levels.

  1. Nice to see that you published my yet unfinished project! During a so called FedEx day at ProtoSpace (FabLab Utrecht, The Netherlands) i made a first attempt to connect my Ultimaker to the coin acceptor.
    The only thing is that it has been my first contact with Arduino as 1well… So I have a lot of work to do until it works the way I want it to work. I’ll keep you posted!
