H Bridge Dc Motor Controller. L298n h bridge motor controller drok l298n motor driver board dc dual h bridge robot stepper motor regulator and drives module for arduino smart car power uno mega r3 mega2560 duemilanove. In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water.
L298n h bridge motor controller drok l298n motor driver board dc dual h bridge robot stepper motor regulator and drives module for arduino smart car power uno mega r3 mega2560 duemilanove. Image showing h bridge circuit used for controlling direction of rotation of a dc motor as shown in figure there are two terminals a and b of dc motor. An h bridge is a simple circuit that lets you control a dc motor to go backward or forward.
In this video you will learn how to control a dc motor with the help of arduino uno using an l298n dual h bridge motor controller.
An h bridge is a circuit that can drive a current in either polarity and be controlled by pulse width modulation pwm. When you can control two motors to go either forward or backward you can build yourself a robot. With this shield you can control two dc motor with max current up to 8a with 22v voltage at the same time. Pulse width modulation is a means in controlling the duration of an electronic pulse.
