In this tutorial, we build a robotic arm using 2 servo motors, and we will control them using 2 potentiometers. If you do not know how to use a servo motor, then click here to refer to my previous blog which explains servo motors. If you do not know how to use a potentiometer, then … Continue reading Controlling a Robotic Arm with Potentiometers

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
