Project Overview

This 3-part 3D printed mechanism dispenses euro coins using an affordable SG90 servo motor. Simply program the servo to rotate 180 degrees to automatically push out a single coin.

You can find this project here and modify the parameters for you're own use!: https://makerworld.com/en/models/1648032-parametric-coin-pushout-module#profileId-1742066

For this example the arduino code that i used was:

#include <Servo.h>

Servo myservo;  

const int speed = 300;

void setup() {

  myservo.attach(9);  

}

void loop() {

  myservo.write(0);

  delay(speed);

  myservo.write(180);

  delay(speed);

}
