	Electronics - Prize Dispensing Motor This circuit controls the motor in the prize dispenser. A L293B H-bridge is used to interface between the motor and the C32. In order to drive the motor forwards as well as backwards, two input pins on the H-bridge are needed. Input and output one are used to control the motor’s forward motion while input and output two are used to control the motor’s backward motion. The diodes are used to snub any voltage spikes created when the motor transitions from on to off. The threshold voltage for L293B is 0.9V for low and 3.15V for high, so the C32 can easily drive the H-Bridge.
