Model ship and car controller circuit diagram
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.
