Description: Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take three different kinds of coin! Whether you’re building your own arcade cabinet or just charging admission to your house, this programmable coin acceptor makes it easy to monetize your next project.
The sensors in this coin acceptor use the thickness, diameter and fall time of the coins to identify them and it’s fully programmable so you’re not limited to any particular type of currency. Simply use the buttons and 7-segment display on the side of the unit to select a coin profile, insert a bunch of coin samples (or the same one, over and over) and you’re good to go! After you’ve programmed the coin profiles, the coin acceptor will recognize them and report when each type is inserted, rejecting other coins.
So maybe you won’t get rich building your own vending machines but access control using different sizes of tokens might be cool, or even a virtual vending machine where you can buy MMORPG items. There are a ton of cool coin-operated projects just waiting to be built!

I bought this for an arcade project that I was working on. By the time I got everything together the last 3 things to hook up was this product and my raspberry pi 3 and monitor. My code is sound, everything looked good. For some reason my call to wait_for_edge was constantly triggering even though a coin wasnt deposited. My buttons were going crazy, throwing errors everywhere. Everything is soldered, everything is heatshrinked, I know my code is good. I stayed up last night, determined to find the problem, until 4 am. Magically my code just started working and everything was smooth. But why? I chalked it up to I was tired and missed something and didn’t remember correcting it. The next day I went back after it. The same problem occurred. At midnight tonight I have finally truly found the problem after the magic smoke came out of my brand new pi 3. This device and it’s terribly thought out pin arrangement and poor pigtail cable, had a small short somewhere in the connector. It crossed the 12v lead to the output pin and that turned into over a $60 loss with my new pi and this coin acceptor.
Ps, it’s not made of metal like it looks like in the picture, that’s chromed plastic.
I’m sorry to hear about your issues with the coin acceptor. We do not usually see any issues with the coin acceptor. This sounds like an isolated incident.
If you can provide an email to firstname.lastname@example.org with your order number with your coin acceptor and Pi3, we can assist you further.
Programming can be a nuisance and at one point while trying to reprogram it it stopped working and blinked “00” with every valid coin. I toggled one of the switches on the back and it worked again after another reprogramming. I might be ordering more of these soon!
