hopper-metering-tool

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

Wire:

• 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
