Gear DC Motor, B O motor, servo motor, stepper motor etc. A DC motor have two terminals, and it can rotate in both directions clock wise and Anti clockwise. If we connect its one terminal, to the positive supply and connect the other one with the negative supply then it will rotate in any one direction either clockwise or counter clockwise, and if we reverse the supply then it will reverse its direction. To manually control a motor, we need a battery a motor and a switch, by this way we can just turn on or off the motor, and it will rotate in only one direction. We can do the same work automatically by using a Transistor. When transistor will get a high pulse then it will turn on and on the motor. To rotate the motor in both the direction, we need 4 transistors. This configuration is called H bridge. In this configuration, when transistor Q 1 and Q 4 are on, then motor rotates in one direction, and when, Q 2 and Q 3 are on, then motor reverse its direction. L293D is a Motor driver IC which has two H-bridge inside it. It can control two DC motors. This is the pin diagram of L293D. V c c, and ground pins are connected to the positive and negative terminal of power supply. Enable 1 2, input 1 and input 2 are used to control the motor’s direction. These pins can be connected to any microcontroller or Arduino. output pins are connected to the motor. When enable 1 2 pin will get a high signal, then it enables the output of one side. On the other side of the IC Enable 3 4, input 3 and input 4 are used to control the second motor. This is the table which shows the controlling of motor. When we give a high signal to enable 1 2 pin, high signal to Input 1 and Low signal to Input 2 then Motor rotate clockwise and when we give low signal at Input 1 and high signal at Input 2 then motor rotate anti clockwise. When enable pin is low then motor stop rotating. this was some basic information about L 2 9 3 d motor driver IC. i hope you get some useful knowledge. thank you so much.
