RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

A simple interactive Arduino UNO project to control 4 servo motors (SG90) simultaneously. Each servo is connected to a digital pin and moves in sync from 0° to 180° and back in a smooth motion. 1 D3 ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

There are plenty of Arduino weather station tutorials available to follow but one published by Kutluhan Aktar not only displays whether information and activate RGB colour patterns but it also ...

The Arduino is a cheap, fun way to get into building your own electronics. It can also be daunting to get started. Here, we’ll show you how to get a start-to-finish Arduino primer with a killer ...

If you would like to learn more about how jet engines work you may be interested in this new DIY Arduino project published by the DIY GUY. The tutorial takes you through how you can create your very ...
