Electromechanical Control Using the Arduino

Abstract

DC motors are becoming increasingly common in a variety of motor applications such as fans, pumps, appliances, automation, and automotive drive. The reasons for their increased popularity are better speed versus torque characteristics, high efficiency, long operating life, and noiseless operation. In addition to these advantages, the ratio of torque delivered to the size of the motor is higher, making it useful in applications where space and weight are critical factors. This makes them attractive options for designers who are interested in robotics. You can run a DC motor by supplying a voltage difference across its leads. However, you need to overcome certain challenges in order to drive them effectively. The most common goals are variable speed and direction. To control the direction of the spin of DC motors, without changing the way that the leads are connected, an H-Bridge is commonly used.
