So you’ve already blinked some LEDs like a pro? Nice. But what if we want the LED to fade in and out — like it’s breathing, like it’s alive, like… your ambition every Monday morning? Let’s make your Arduino control…
Have you just learned how to blink one LED with Arduino and you’re thinking… “Okay cool, now what?” Well, how about we blink multiple LEDs like a pro? In this post, I’ll show you how to connect and blink 3…
So you’ve mastered the basic LED blink using delay(). Feels good, right? But here’s the thing: delay() is kind of a beginner trap. It stops everything while it waits — like freezing your whole code just to blink a light.…
Want to visualize how close something is using just LEDs? In this project, we’ll use an HC-SR04 ultrasonic sensor to light up a row of LEDs based on distance — the closer the object gets, the more LEDs light up.…
In this upgraded version of the LED temperature meter, we’ll display the current temperature in real-time on a 16×2 LCD alongside the LED bar. The LEDs light up based on temperature level, while the LCD gives you the exact number…
Want to build a DIY countdown timer with a raw 7-segment display, without any fancy modules like TM1637? Let’s do it the hardcore way — controlling each segment manually using Arduino pins. This is a great project to understand how…
In this project, you’ll learn how to control a multi-LED chaser effect using just one button. This tutorial covers how to: It’s a fun way to explore INPUT_PULLUP, button debouncing, and LED animations — all with clean, beginner-friendly code. Components…
Create an LED Chaser Effect with Arduino (Multiple LEDs + Button Control) An LED chaser (also called LED running lights) is a popular beginner Arduino project where multiple LEDs light up one after the other, creating a chasing or bouncing…
Controlling an LED with a pushbutton is one of the best starting points when learning Arduino. In this tutorial, you’ll learn how to wire a simple circuit and write basic code that lets you turn an LED on and off…
In this tutorial, we’ll build a simple but powerful Arduino LED Dimmer using a potentiometer and PWM (Pulse Width Modulation). You’ll get to understand how PWM works, and how you can control the brightness of an LED based on the…
