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 get the files here: 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); }
