Whether you prefer to unwind the evening with a good book, play games on your phone, or wanna have some cozy time with your partner, the right bedside lighting can make a lot of difference. In this project, I am going to make a touchless multipurpose bedside lamp, which will also include a digital clock, two power-ports and a USB charger. Sponsors This video is sponsored by PCBWay.

Have an awesome project in mind using some LEDs. In that project I will be using some LED Fading Effect and few LED Chaser Circuits. But before jumping onto that, I thought I should create a short tutorial and show you guys how to fade a LED with or without an Arduino automatically or manually using a potentiometer.

A Chaser Circuit consists of a clocked IC or other electronic unit like an Arduino that drives an array of LEDs in such a way that individual LEDs (or small groups of LEDs) turn on and off in a predetermined and repeating sequence, thus producing a visually attractive display in which one or more ripples of light seem to repeatedly run through a chain or around a ring of LEDs. In this tutorial I am going to create 3 chaser circuits using Arduino and IC4017 decade counter. https://youtu.be/F6V1AjESWbU Sponsors

Trying to explain dialup to a pre-teen will evoke the same wild-eyed bewilderment as “a dinosaur was as-big-as this house”. We can’t go off what our parents did because two tin cans connected by a string isn’t really the same these days and probably it would look like a piece of junk for the new and upcoming generations. However, the truth is "life is busy" and hence we don’t spend enough time with our children. Children need high-quality time with parents and caregivers - the QUALITY of time spent with them is much more important than the QUANTITY of time. Christmas was

Tutorial - Reed switch Reed switch was invented in 1936 by Walter B. Ellwood in the Bell Telephone Labs. Reed Switch consists of a pair of ferromagnetic (something as easy to magnetize as iron) flexible metal contacts typically nickel-iron alloy (as they are easy to magnetize and doesn't stay magnetized for long) separated by only a few microns, coated with a hard-wearing metal such as Rhodium or Ruthenium(Rh, Ru, Ir, or W) (to give them a long life as they switch on and off) in a hermetically sealed (airtight) glass envelope (to keep them dust and dirt free). The glass tube contain

The very first program you write when you start learning a new programming language is: "Hello World!". The program itself does nothing more than printing a “Hello World” text on the screen. So, how do we get our Arduino to display the "Hello World!"? In this video, I will be showing you how to get started with the small 0.91 (128x32) and 0.96 (128x64) I2C OLED displays. There are 100s of tutorials on the web explaining the same thing in different ways, but I couldn't find one that tells me all about the OLED display and how to use it in different scenarios. It took me some

Has this ever happened to you? You come back from a romantic dinner date and when you open the shutter door of your garage you realize that you left the garage light ON. You spent few hours outside with your partner to impress her and all the time this light bulb was on. You immediately turn around and look at her face to see a silent anger on her face. Alright, enough of that. So, in this tutorial, I am going to turn on and off the garage light using a PIR sensor. When the sensor detects a moving object, it turns on the light bulb and when the moving object is gone, it turns it off. Last

Just before creating my next projects tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial explaining the working of a PIR sensor. By doing that I will be able to keep my other tutorial short and to the point. So, without wasting time let’s discuss what is a PIR sensor and how we can use it in our project. Step 1: Basic What is a PIR sensor? PIR or "Passive Infra-Red" sensor is a "Pyroelectric IR Sensor" which generates energy when exposed to heat. Everything emits some low level of radiation, the hotter the object is, the m

DRIVING A RELAY WITH AN ARDUINO Hello everyone, welcome back to my channel. This is my 4th tutorial on how to drive a RELAY (not a relay module) with an Arduino. There are hundreds of tutorial available on how to use a "relay module" but I could not find a good one that shows how to use a Relay and not a Relay module. So, here we are to discuss how a relay works and how we can hook it up to an Arduino. Note: If you do any work with "mains power" such as 120v or 240v AC power wiring, you should always use proper equipments and safety gears and determine whe

Introduction ---------------- Hi Friends, I am back again with another Arduino based home automation project. This time I am trying to make my partner's life easy by installing a collision avoidance system in the garage to help her park the car safely without hitting the garage wall. So, in this video, I am going to use an ultrasonic sensor to calculate the car's distance from the garage wall and display it using green, yellow and red LEDs. The color of LEDs indicates whether to keep moving, slow down, stop or go back. The total cost of the project is around $20 - $25.

Introduction --------------- Hi Everyone, This is my 1st Arduino's tutorial video. In this video i am going to show you how to use a LDR or Light Dependent resistor to turn on and off another circuit or a LED. Wouldn’t it be really cool if whenever a room gets dark, a light bulb automatically turns ON and eliminates the darkness? In this very simple project, I am focusing on eliminating darkness. You can even use this as an emergency lighting system. Step 1: Principle The LDR is a special type of resistor which allows a l

Hi Everyone, In this tutorial I am going to show you how to charge a Lithium 18650 Cell using TP4056 chip utilizing the solar energy or simply the SUN. Wouldn’t it be really cool if you can charge your mobile phones battery using the sun instead of a USB charger. You can also use this project as a DIY portable power bank. The total cost of this project excluding the battery is just under $5. The battery will addup another $4 to $5 bucks. So the total cost of the project is some what around $10.
