L293D IC Motor Driver Servo Driver go with I2CL293D is a dual H bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low current control signal and provide a higher current signal. This higher current signal is used to drive the motors. L293D contains two inbuilt H bridge driver circuits. In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be
