Solder the ground wire to the ground pin on the bill acceptor.
Solder the neutral wire to the "110v AC neutral" pin on the bill acceptor. Solder the hot wire to the "110v AC hot" pin on the bill acceptor. You should always check with a multimeter but usually black is hot, white is neutral and green is ground. Usually the wires will be black, white and green. If it accepts a bill then you did it right. The bill acceptor should power up, make some noise and the LEDs on the front should start blinking. One you've done this, plug the 12v power supply into a socket. Solder the positive wire from your 12v DC power supply to the "12v DC positive" pin on the bill acceptor and the negative wire from the power supply to the "12v DC negative" pin on the bill acceptor. Cut the barrel jack off and use a multimeter to find out which wire is postive and negative. You can use a normal 12v DC power supply, e.g. You should also connect the arduino ground pin to the same ground as the bill acceptor, however, if the computer the arduino is plugged into is already grounded to the same ground then it will probably be fine with just the two pulse pins connected. Solder another wire from the "pulse -" pin to the input pin on the arduino (the one with the 10k resistor connected). Now solder a wire from the "pulse +" pin from the bill acceptor to the 5v pin on the arduino. This is to prevent current from flowing into the input pin when the input pin gets connected to +5 volts during pulses. Now, on the back of the arduino, solder a 10k resistor between pin 10 and the GND pin.
It makes sense to choose one closer to the ground (GND) pin. Connecting to Arduinoįirst, choose an input pin on the Arduino. Remember that when looking at the pins from below the PCB the bottom row corresponds to the top row in the diagram and vice-versa. I recommend sliding off the plastic cover below the pin connector and accessing the pins where they are soldered onto the circuit board of the bill acceptor, since it's otherwise quite hard to maneuver a soldering iron (+ you retain the ability to connect a wire harness later). Pinouts 12v DC version Wiring harness pinoutĪssuming you have the wiring harness (the short cable sticking out from the bill acceptor and terminating in a 9 pin square connector), use this pinout. This guide should work for any bill acceptor or coin acceptor that functions in this manner. You have two wires connected between your Arduino and bill acceptor and for every pulse the bill acceptor shorts the wires (connects the two wires together). The ICT bill acceptor pulse output functions similar to someone pressing a button once for every dollar. This guide uses the pulse interface from the bill acceptor even though some of these bill acceptors also have a serial interface.
Working juul serial codes update#
You may be able to save money by getting one that doesn't take the new $5 bill and buying a separate update chip for about $15 (just search ebay for ICT update chip). Make sure you get a bill acceptor that accepts the new $5 bills. a desktop computer (for 110v AC bill acceptor)
Working juul serial codes how to#
This guide shows how to connect an ICT bill acceptor with pulse output to an Arduino Leonardo and includes code for the Arduino that will make it act like a USB keyboard. Converting ICT bill acceptor pulse output to USB keyboard keypresses or serial over USB.
