H Bridge Pwm Dc Motor Control. The four h bridge dc motor direction control pins will now be pulled high or low depending on the motor direction required. High efficiency rotation direction change and braking the motor.
The l298n is a dual h bridge motor driver which allows speed and direction control of two dc motors at the same time. These are dual h bridge motor drivers i e by using one ic we can control two dc motors in both clockwise and counterclockwise directions. Here is the complete circuit.
The main advantages of using an h bridge driver are.
An h bridge is a simple circuit that lets you control a dc motor to go backward or forward. Motors as a class require very high currents to operate. Being able to vary their speed with pwm increases the efficiency of the total system by quite a bit. High efficiency rotation direction change and braking the motor.
