Multi Coin Acceptor - Programmable 6 Coin Type

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. This model has the cool ability to accept up to 6 different coins! For example, you can program it for 6 different US coins, or European, or Japanese OR you can have it accept 6 coins from different countries - say a Chinese Yuan, Japanese Yen, American Quarter and European Euro. First you'll have to program it with what coins you want it to accept. Any coin from 15mm to 29mm in diameter can be used. Each coin is assigned a number of pulses, so for example, a nickel should be 1 pulse, a dime, 2 pulses, a quarter 5 pulses and a half dollar 10 pulses. 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.

Comes with the acceptor itself, mounting hardware, and a cable for power/signal. The coin falls through, you choose how and where to store them.

You'll need about 20 of each coin to help program the acceptor. After programming, connect a 10K (1K to 100K is fine) pull-up resistor from the white wire to your microcontroller's VCC line (for Arduino, this is a +5V). Insert different coins, and verify that the coin line pulses high for about 40 milliseconds the right number of times.

User Guide

Setup Process

1. Press the "+" and "-" buttons at the same time for three seconds, then the letter "A" will display in the LED display.
2. Press the "setup" button once for "E" , now select how many difference kinds of coins you would like to use.
3. Press the "setup" button once for "H" , press "+" and "-" buttons to choose how many samples you would like to insert.
     ​Suggest to select 20 (Repeat the same kind of coin for sampling)
4. Press the "setup" button once for "P" , press "+" and "-" buttons to choose the output's signal / pulse you want.
     The quantity limited to 50 times.
5. Press the "setup" button once for "F" , press "+" and "-" buttons to choose accuracy.
     The value is from 1~30, and 1 is the most accurate. Suggest to select 8.
6. Press the "setup" button again to continue.
7. The letter "A" will display again after all above procedures are finished.
8. Press the "setup" button, and the letter "E" will display. Finally, turn off and turn on the power. The setup will be stored.
9. You can start sampling after this setup is finished. The sampling process will affect the accuracy of coin selector.

Sampling 

1. Press the "setup" button, then letter "A" will display  in the LED display.
2. Press the "setup" button again, then "A1" will display.
3. Start to insert sample coins. The LED display will show how many coins you insert. The letter "A1" will display again after finished.
4. Press the "setup" button again, then the letter "A2" will display.
5. Start to sample 2nd coin, and repeat step 1 and step 2 until all the coins are setup.
6. After finished the sampling, press the "setup" button.
7. Then turn off and turn on the power.
8. Now you can start to use it.

FAQ

Coins can't pass through

• Check if the connection is correct or poor connection.
• Check if sampling is appropriate.
• Check if there is something stuck inside.

Can't identify outputs

• Check if 2 way switches -NO. NC.- are correct.
• Check if Singal wire is connected correctly .
• Check if there is pull-up resistor with signal wire(not allowed).
• Check if there is something stuck on the channel where the coins pass out.

Coins can not pass smoothly

• Check if the parameter is set up appropriately.
• Check the accuracy switch
• Check if there is something stuck on the channel where the coins pass out.
