Arduino projects, tutorials and guides you can build with parts from Arduino Corner.
No app, no hub, no account that can be discontinued. Six mains-powered upgrades under Rs 2000 that keep working during load shedding and internet outages — and the order to buy them in.
Lighting an LED from an Arduino pin is the first real circuit almost everyone builds. It takes three parts — an LED, a resistor and a jumper wire — and teaches the two rules you’ll use forever: polarity and current…
The Arduino Uno has a row of pins along each side, and knowing what each does saves you from guesswork and fried components. Here’s the plain-English map. In short: The Uno’s pins fall into five groups: power pins, digital pins…
A breadboard lets you build and change circuits with no soldering — just push components and wires into the holes. But those holes connect in a specific pattern, and understanding it is the difference between a working circuit and an…
You’ve got your board — now let’s make it do something. In ten minutes you’ll install the software and blink an LED, the “hello world” of electronics. In short: Download the free Arduino IDE, install the CH340 driver if your…
You’ve heard the word everywhere — in robotics clubs, FYP discussions, YouTube projects. So what actually is an Arduino, and why does everyone learning electronics start with one? In short: An Arduino is a small, cheap, programmable circuit board. You…
Under-voltage kills more compressors than spikes do. What a voltage protector actually does, how it differs from a stabiliser and a UPS, and the four settings to get right.
A first robot car is the project that hooks most people on electronics. But it needs several parts that must work together — get one wrong and it won’t move. Here’s exactly what to buy. Short answer: For a first…
Starting a final-year project and not sure what to actually buy? Most FYPs in electronics, mechatronics and CS share the same building blocks. Here’s a practical checklist you can adapt. Short answer: Almost every hardware FYP needs: a controller (Arduino…
Almost everyone learning Arduino asks the same thing: do I buy a starter kit, or just the board and pick up parts as I go? Here’s the honest answer. Short answer: For a beginner or a student, the Arduino Uno…
Sensors are what make a project do something — they let your Arduino measure the world and react. But there are hundreds of them. Here are the ones actually worth starting with, what each does, and what you can build.…
If you’re buying your first Arduino, the number of options is overwhelming — Uno, Nano, Mega, ESP32, dozens of clones. The good news: for a complete beginner the answer is simple. Short answer: Buy the Arduino Uno R3, or better…
When your robot needs to “see” an obstacle, two cheap sensors compete for the job: the HC-SR04 ultrasonic sensor and the IR obstacle sensor. They solve the same problem in completely different ways, and each wins at a different task.…
The oldest piece of automation in the trade and still one of the most useful. Three wires, no timer to reset — and one mounting mistake that makes people think the unit is faulty.
An Arduino pin can’t drive a motor directly — it can’t supply enough current, and the motor’s electrical noise would damage the board. A motor driver sits in between. The two you’ll meet first are the L293D and the L298N,…
