In this project, I have explained how to control motor speed using Arduino PWM circuit, and how to implement reverse forward or direction control in a DC motor using Arduino through a couple of push button switches. Any high current motor upto 30 amp can be controlled using this set up. Introduction Motor is a […]

How to Control Servo Motor Using Joystick
In this post I have explained how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will be extracting useful data from the joy stick which will be base for controlling the servo motors. Introduction The motto of this article is not […]
Wireless Servo Motor Control Using 2.4 GHz communication link
In this post I will show how to construct a wireless servo motor circuit which can control 6 servo motors wirelessly on 2.4 GHz communication link. Introduction The project is divided into two parts: a transmitter with 6 potentiometers and a receiver circuit with 6 servo motors. The remote has 6 potentiometers to control 6 […]
Build this Unidirectional Wind Turbine: Wells Turbine
In this article I will explain you the full step by step building guide for making one Wells turbine at home, which is intended specially for homemade sea wave electricity system using oscillating air column. What is Wells Turbine So first we must understand that wells turbine is a special type of turbine in which […]
Simple 220V AC Fan Regulator Circuit using Push Button
In this post we learn about this 220V AC electronic fan regulator circuit using a push button which changes speed step by step with each press. We press the button, then circuit cleans the signal, counts it properly, and then selects a relevant fixed speed level. Each button press moves the fan from OFF to […]
A4988 Motor Driver Circuit Diagram with IC 555
In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]
