DC motor driver and relay driver in DAS

The main purpose of DC interfacing with 8051 microcontroller is for controlling the speed of the motor. The DC motor is an electrical machine with a rotating part termed as a rotor which has to be controlled. For example, consider the DC motor whose speed or direction of rotation of DC motor can be controlled using programming techniques which can be achieved by interfacing with 8051 microcontroller.

In some electronic applications we need to switch or control high voltages or high currents. In these cases we may use electromagnetic or solid state relays.
