Want to make an arcade game or vending machine? Maybe you want to charge customers to use your awesome invention – but how? Look no further! Coin acceptors have become inexpensive enough for anyone to purchase, so this tutorial is designed to show you how to connect one to your Propeller-powered BlocklyProp project.
Hardware Required
- (1) – Coin Acceptor (this project specifically uses this one from Amazon)
- If you choose a different coin acceptor, you may need to make modifications to the instructions. Consult your device’s manual.
- (1) – 12 VDC power supply (#750-00003)
- (1) – 10 k-Ohm resistor (brown-black-orange) (part of #751-00011)
- 3-pin cable:
- Propeller development board:
- (1) – Propeller Activity Board or Activity Board WX (#32912) OR
- (1) – Propeller FLiP (#32123) plus:
- (1) – 3-pin breadboard header (#451-00303)
- misc male/male jumper wires (#800-00016)
- Note: The header, breadboard, wires and FLiP can be purchased separately or you can get them (and more) together in the Propeller FLiP Try-it Kit (#32023).
- Misc coins to program the coin acceptor with (20 of each type of coin is best)
NOTE: The 12V supply can be connected to the (→5-9VIN pin) on the FLiP – however be aware that because the input voltage is above 9 volts, if the FLiP module’s power connections are shorted, the FLiP will get VERY HOT.
