bidirectional transistor motor driver for robotic project/ H bridge motor driver

this is the very useful motor driver circuit and its easy to make. this circuit is used in robotic project to move the robotic wheel front back right and left. this circuit is composed of two npn and two pnp transistors and some resistor. you need to have two switch to change the direction of the motor. here the transistors are acting on the its switching application. when both switches are off then motor donot move. when one of the switch is on then the npn of the one and the pnp of another side will be on so current flow through motor. so motor is on. when upper pnp is on on the left side, its lower npn is of and right side lower npn will be on but right side upper pnp will be off when switch is pressed at right side. note switch on means logic 0 and switch off means logic 1 if you are facing problems you can comment here. for the full description i ll upload the working video on youtube.com. check my channel sangit.niroula. this circuit is simulated in proteus simulator.
