Uses an Arduino to meter coins out of an Suzohapp MKII Cube Hopper at an exact interval.
This works great and is used in production.
Tasks for next build:
- Post a picture of the current build.
- Test if the whole hopper can be turned off instead of just the motor.
- It would be nice to print a circuit board for this.
It gets input from the cube hopper's open-collector output time the power on the motor.
A general page on an open-collector circuit details: http://www.evilmadscientist.com/2012/basics-open-collector-outputs/
Hopper Wiring Notes:
- Only 5 wires need to connect to the hopper: (Pretend it does not have power like a Ryedale)
- A 6# (Signal)
- B 8# (Ground)
- C 9# (12V Positive)
- D Black from the motor (Positive: Hopper is wired backwards from the factory)
- E Red from the motor (Ground: Hopper is wired backwards from the factory)
- The motor is no longer connected to the hopper control board.
Arduino Takes 12V in with the Barrel jack
- A To Arduino Pin 0
- B Ground on the Arduino
- Solenoid NC
- Ground PIN on the Relay board
- E (Ground - Red on Motor)
- C VIN on the Arduino
- Solenoid NO
- E Solenoid COM
- 5V Arduino To 4700 Ohm then Arduino Pin 0
Relay Module Board Controls:
- (The input pins must be pulled to ground for the relay to turn on. )
- VIN to 5V on the Arduino
- Input 2 to PIN 9 on the Arduino
- Ground to Ground
