With the increasing demand for automation and remote operation, controlling electrical devices without the need for physical access has become an important area of development in modern engineering.

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

This project implements speed and direction control of a DC motor using an Arduino Uno and an H-Bridge motor driver (L293D). The system allows the user to control the motor rotation direction using ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the PC ...
