The 2-wire control circuit uses maintained contact devices to control the magnetic motor starter. The 3-wire control circuit uses momentary contact devices to control the magnetic motor starter.

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

introducing beginners to H-bridge motor drivers. While many of you will consider this stuff basic, those who are trying to expand from building only things the arduino board can handle to bigger ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at ...

You can salvage some nice motors out of optical drives but they can be tricky to control ... Arduino and has a couple of posts explaining the concept and demonstrating how it works. His test ...

Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software. Add a motor and motor control circuit into a microprocessor based development kit. Create ...

The key to developing a logical and systematic approach to troubleshooting motors and controls is to first understand the overall concept of the motor and its associated control circuit — and then use ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking ...
