Completing an Arduino project gives you a sense of satisfaction like no other. Problem is, it’s very easy to run out of ideas for a project. Sure, there are a lot of projects and ideas throughout the internet but you have to spend a lot of time to find the ones that are really interesting.

That’s why, from now on, we’ll be bringing you 3 Arduino projects every week which we find interesting. We hope they’ll inspire you to go on and do more with your Arduino! So, let’s start…


3. Arduino Metal Detector

Metal detector is a security device which is used for detecting metals which can be harmful, at various places like airports, shopping malls, cinemas etc. In this project, you are going to use a coil and capacitor which will be responsible for the detection of metals. This is very interesting projects for all electronics lovers. Wherever this detector detects any metal near it, the buzzer starts beeping very rapidly. Learn how to do it here.


2. Arduino Propeller LED Display

You have seen propellers in aircrafts or in marine ships, if not in real then in movies for sure. In this project you are going to build a propeller display with Arduino, LEDs and a DC motor. Text will appear to be rotating in propeller fashion in a circular shape. This is achieved by Perception of Vision (POV), in which many still images are moved quickly one by one in a sequence, which gives a perception of animation or a moving image. How this is done is explained here.


1. Arduino Lightsaber

A color changing lightsaber based on Arduino technology. It’s an intermediate project that will teach you how to make a lightsaber that is relatively easy to wield and that will teach you how to have it make sounds on ignite, extinguish and general use.
