Infrared (IR) remote controls are everywhere these days — you’ve probably used them to control your TV, speaker system, air conditioner, fan, or even to switch a light on and off. But here’s the cool part: you can also use…
Signals form the basis of communication in electronic systems, allowing devices to transmit and process information. Broadly, signals can be classified into two fundamental types: analog signals and digital signals. In this comprehensive guide, we’ll dive deep into the specifics,…
Digital signals are binary — they can only be either 0 or 1. Analog signals, however, have a continuous range of values and are not limited to just two states. Both types of signals are found in electronic systems, but…
Whether you’re building your first project or just need a refresher, this guide walks through all the key pins and onboard components of the Arduino Nano. We’ll cover power inputs, I/O, communication protocols, and what each part of the board…
So you just got your Arduino Uno and you’re staring at this blue board full of mysterious pins… What the heck is “A0–A5”? What’s “VIN”? And what happens if you stick a wire into “RESET”? Don’t worry – in this…
Ever wanted a night light that just knows when to turn on? In this project, we’ll build a simple automatic night light using an Arduino and an LDR (light-dependent resistor). When it gets dark, the LED turns on. When it’s…
Ever watched Knight Rider — that 80s show with the talking car KITT? If you have, you probably remember the sleek red lights on the front of the car that scanned left and right. In this project, we’re going to…
If you’re just getting started with Arduino, you’ve likely come across two of the most popular boards: the Arduino Uno and the Arduino Nano. Both are powered by the same microcontroller — the ATmega328P — and support the full range…
How to Make a Line Following Robot Using Arduino and L293D (Beginner-Friendly Guide) Have you ever dreamed of building a robot that moves by itself, follows a path like it’s alive, and actually understands the world around it — well,…
How to make a DIY Bluetooth-Controlled 4WD Robot Car Hey makers! Let me tell you a quick story. A few weeks ago, I was at home, staring at a bunch of leftover parts from older Arduino projects—motors, wheels, a dusty…
