This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller ... Before writing the program to the PWM mode we need to know the ...

This project involves controlling the start and stop of a stepper motor using an 8051 microcontroller. The stepper motor is connected to the microcontroller through a motor driver circuit ... as push ...

Here we design a simple non-contact tachometer using microcontroller, which can measure speed with an accuracy of 1 rev/sec. Principle Behind the Circuit ... program, it accordingly increases the ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor ... program (see the listing below) was converted into a hex machine-code file using the ...

This project demonstrates how to control both a stepper motor and a DC motor in the same circuit using an 8051 microcontroller ... motors can be triggered independently via push buttons or program ...
