Pin 3: Output 1, this pin is connected with one terminal of motor. Pin 2: Input 1, when this pin is HIGH the current will flow though output 1. Pin 1: When Enable1/2 is HIGH, Left part of IC will work, i.e motor connected with pin 3 and pin 6 will rotate.

There are 4 INPUT pins, 4 OUTPUT pins and 2 ENABLE pin for each motor. The L293D is a 16 pin IC, with eight pins, on each side, to controlling of two DC motor simultaneously. In these waves frequency is same but the ON and OFF times are different. These diagram below shows the waveforms obtained as output at different voltage requirements

The PWM controller accepts the control signal and adjusts the duty cycle of the PWM signal according to the requirements. The input signals we given to PWM controller might be an analog or digital signal according to the design of the PWM controller. The speed controller PWM for a DC motor works by varying the average voltage supplied to the motor But in practice, for changing the speed of a dc motor we cannot go on changing the supply voltage all the time. The DC motor speed in general is directly proportional to the supply voltage, so if reduce the voltage from 9 volts to 4.5 volts then our speed become half of what it originally had. This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V. This Motor Driver is designed and developed based on L293D IC. The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously.
