2 jumper pins are used to connect Enable pins to 5V. We can connect 7-30V to this circuit through IC 7805 voltage regulator or 5V directly. In this circuit, I used 4Г—1 male header pins for Input, 5Г—1 male header pins for power supply. These pins are connected to motors Pin 3,6 to one motor and Pin 11,14 to another one. LetвЂ™s see the truth table it helps you to understand how it changes the direction of the motor And Input 1,2 is for one motor and input 3,4 is for the second motor. These pins in actual changes the polarity of output pins. These pins are usedВ to control the direction of motors clockwise as well as anticlockwise.

And in case of Arduino & microcontroller speed of motors will be controlled with the help of PWM(Pulse width modulation).

When you connect this pins directly to 5 volt than your motor will rotate at its full speed and if you connect it with 2.5 volt than motor will rotate at its half speed and if no voltage is connected toВ these pins than motor their will be no rotation. Similarly Enable 3,4 have control over another motor. Enable 1,2 means this pin(1) have the control over 2 output pins(3,6) means one motor. These 2 pins helps us to control the speed of both the motors individuallyВ if. You can choose any pin from these 4 pins and connect to ground. These pins are interconnected internally so no need of attaching all the pins to ground(Zero Volt). Let us say you are using motor that requires 9 Volt than you have to connect voltage source of 9 volt to this pin. This pin is connected to voltage source according to your motors voltage requirement.

If you are using more than 5 volt you can use 7805 voltage regulator for 5 volts conversion. This pin is directly connected to +5 volt which is required for its internal circuit of IC. It means that you can control twoВ DC MotorВ with a single L293D IC.

L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. The L293D devices are quadruple high-current half-H drivers.
