The four remote switching circuit is shown as above. It uses ZS-01F memory self-locking type bistable relay, so the remote control receiver circuit in the circuit output pulse signal will open the related control functions. However, the circuit also exists such a problem: As the control circuit's on and offbuttons usesthe same remote transmitter button, sometimes due to the phenomenon of false positives caused by misuse, this circuit is not allowed for some accused appear. This control circuit will switch to another relay in the relay, the remote control transmitter. Respectively, it uses two different keys to control the circuit on and off, so opening and closing control is clear, you can avoid the misuse phenomenon. (View)

NE556 is a dual time base IC, whichcontains two separate 555 circuits. Each 555 circuit forms a Schmitt trigger. The flipping of trigger is achieved by TX315B1 output control. When the Schmitt trigger input is low, its output terminal outputs high level; When the input is high, its output terminal outputs low level. When the both ends of the motor are high or low level, the motor stops; When the motor is high at one end, the other end is low, the motor rotates; If the ends are high and low swap, then The direction of motor rotation is opposite.
