Travel schematic model remote control

  
As shown in FIG travel remote control model is a circuit diagram, NE556 is a dual time base IC 555 includes two separate circuits, each consisting of a Schmitt trigger circuit

555, the output of the control TX315B1 realized by flip-flop flip. When the input of the Schmitt trigger is low, its output terminal output high; when the input is high, its output of low output. When both ends of the motor are high or low, the motor is stopped; when both ends of the motor is high end, and the other side is low, the motor rotation; if the motor across the high, low swap, reverse the direction of rotation of the motor.
