This project explains how to build a fully automatic ultrasonic water level controller where the water pump motor starts automatically when the tank level goes below a preset LOW level and stops automatically when the tank becomes FULL. The whole system is wireless, reliable, and there are no corrosion problems because the ultrasonic sensor never […]

High Current Motor Control Circuit using Arduino
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 […]
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 […]
How to Control a Servo Motor using IC 555
In this project I have explained the basic specifications of a servo motor and also how to control a Servo Motor using a 555 timer IC, and just two push buttons. WHY SERVO? Servo Motors are used in variety of fields. These are mainly used as actuators in those areas where we need a precise […]
