Fidget Spinner Electricity Generator

In this project, we are going to build a simple generator using an electromagnet and a fidget spinner to understand the concept of the electric generator.

Arduino Relay Control

Arduino Relay Control

Whenever we need to connect any AC Appliance in our embedded circuits, we use a Relay. So in this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control relay.

DIY Brushless Motor Using Fidget Spinner

Just like the craze for Pokémon Go out of nowhere the fidget spinners got popular and it became more of trend to have one of these spinning between your fingers. But lately people (including me) eventually got bored of it and hence in this project let us bring in a new purpose for fidget spinner by building a simple motor using Fidget Spinner. With this circuit you will be able to make the fidget spinner rotate forever with the help of basic physics and not worry about having it idle at some corner of your room. You will also learn the basic of how a Brushless DC motor works since the concept we are using here is same as that used in the famous BLDC motors.

Different Types of Switches and Their Applications

There are mainly two types of switches- mechanical switch and electrical switch. Mechanical switches require physical or manual contact with switch for operation. Electrical switches not require physical or manual contact, it has ability to perform operation. Electrical switches operate under the action of semiconductors.

How to Connect 2-Way Switch

How to Connect 2-Way Switch

There are two methods of making 2-way switching connection one is 2-wire control and another is 3-wire control. We have explained both the methods below and both the methods are demonstrated in the Video given at the end of this article.

Smart Blind Stick using Arduino

This Smart stick will have an Ultrasonic sensor to sense distance from any obstacle, LDR to sense lighting conditions and a RF remote using which the blind man could remotely locate his stick. All the feedbacks will be given to the blind man through a Buzzer. Of course you can use a vibrator motor in place of Buzzer and advance a lot more using your creativity.

LED Roulette Circuit

Here, we are going to show you how to make an LED Roulette Circuit using 555 timer IC, before starting the tutorial let you know about what the roulette is, it’s a casino game named after the French word which means little wheel. As same, here we are making a wheel (or circle) shaped led blinker, using 555 timer IC placed in Astable mode, and IC 4017 which is decade counter IC and small needful components.
