Prize Dispenser

Demo Video This is a completly 3D printed prize dispenser. The arduino controls a servo motor to make a plate spin. The plate has a hole which holds one marble from the container, then moves to the front where it falls into the dispense slot. The arduino also controls the coin detector, which is a photoresistor that detects the shadow from the coin when it passes over the LED across from it. This design requires an Arduino/Genuino Uno, a small servo motor, an LED, a photoresistor, a resistor, a potentiometer and a mix of normal and male to female jumper wires. A hot glue gun can be used to glue the seperate pieces into place. The longer small square is glued on the right side and the shorter small square is glued on the left side.
