In this tutorial we will learn how to control high voltage devices using a relay module. Components needed HW-383 relay Jumper cables Arduino Uno board Light bulb IR Remote Control IR Receiver what is a relay and how does it work? A relay is a switch which is electrically operated by an electromagnet. This relay … Continue reading Remote Control Light using a Relay

How would it work? We will again modify the remote controlled car we built in the previous blog to make it work using joystick instead. Instead of using the remote control to control the car, we will use the IR Transmitter to send the IR signal/code. We will use joystick movement to decide when to … Continue reading Joystick Controlled Car

In this tutorial, we will be modifying the self driving car we built in previous blog to a remote control car. Click here to learn how to build a self driving car using an L298N motor driver module. Components needed L298N Motor Driver 2 DC motors 2 wheels HX1838 IR receiver Remote Jumper cables Arduino … Continue reading Remote Control Car

In this project, we will learn how to make a height measuring device. The height measuring device is a simple device used to measure the height of a person who stands under it. The device will be installed at a certain height and when anyone stands under the device, the height measuring device will measure … Continue reading Height Measuring Device

In this project we will learn how to build a self driving car that avoid any obstacles. Components needed Arduino Uno Jumper Cables 9 volt battery L298N Motor Driver 2 DC Motors 2 wheels 1 caster wheel Ultrasonic Sensor What is an L298N Motor Driver? The image above is an L298N Motor Driver. The L298N … Continue reading Self Driving Arduino Car

A small Arduino project to wish my mom a special Mothers Day. It is simple project where upon asking Alexa "Turn on Mothers Day card" will start the project and couple flowers will do little show (using two servo motors) followed by LCD displaying "Happy Mothers Day" with a flower on top of it rotating … Continue reading Arduino Special: Mothers Day Project
