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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

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!
