Coin Acceptor - Programmable (3 coin types) [COM-11719] - (AD18159)

Description:

Are you trying to make money fast with electronics? Why limit yourself to dimes? This coin acceptor will accept three different kinds of coins! Whether you're building your own arcade machine or just charging admission to your house, this programmable coin acceptor makes monetizing your next project easy.

The sensors in this coin acceptor use the coins' thickness, diameter, and fall time to identify them, and it is fully programmable, so you are not limited to any particular coin types; just insert a bunch of coin samples (or the same one, over and over) and you're good to go! Once you've programmed the coin profiles, the coin acceptor will recognize 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 sized tokens might be interesting, 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!
