Description: Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take up to 6 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) then designate the value. After you’ve programmed the coin profiles, simply read the serial output of the coin acceptor and it will tell you the value of each coin as they’re inserted. It reports these values as binary bytes and the baud rate is selectable on the unit.
This coin acceptor also has a coin reject, so your controller can tell the coin acceptor not to take any more coins, as well as a (very loud) alert beeper. All you need to get the coin acceptor working is a pocket full of change, a 12VDC supply and somewhere for the change to fall after it’s accepted.
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 2 coin acceptors. They do everything I wanted and they look great. I connected both of mine to an Arduino Micro and that is connected to my arcade machine PC.
one of the units had a malfunction. immediately after contacting sparkfun, they helped me with it. one of the best customer services I ever got!
I purchased 2 coin acceptors for use in my Pure Water vending machine. They were much easier to program then the ones I removed. I simple told it the value of each coin then sampled them thru the coin acceptor to teach them the weight and size of each coin. I was up an running in no time. The rejection rate is very low only had a problem with really new coins that were not in circulation so the weight was a tad heavier, all the other coins it accepts fine. I Would recommend them for your next project.
After 2 weeks stopped working.
Sorry you’re having trouble with the coin acceptor. I’d suggest sending an email to our tech support team [ firstname.lastname@example.org ], and they should be able to help resolve your issue.
