In the positive mode level control signals open simultaneously the transistor Q1 and Q4 (Q2, Q3) motor positive spin simulation of gift opening.In nghịchcấp mode control signals open simultaneously transistors Q2 and Q3 (Q1, Q4) 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.
