In the positive mode level control signal transistor Q1 and Q4 simultaneously (Q2, Q3 not lead) the motor spin simulation open gift agreement.In inverse mode level control signal transistors Q2 and Q3 simultaneously (Q1, Q4 does not lead) the motor rotating the emulator closed gift.In the model of key groups of children using a one-way motor motor 12V, 800mA to simulate open close door latchesThrough artery can bridge the two motor control signals from the foot of the RB6 RB7, of the microcontroller to control the orientation of the motor.
