How to Build a Temperature-Based LED Bar with TMP36 and Arduino In this project, we’ll use a TMP36 temperature sensor and an Arduino to light up a row of LEDs based on the ambient temperature. As the temperature increases, more…
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…
Making an LED Blink – Your First Line of Arduino Communication Blinking an LED is often considered the “Hello, World!” of microcontroller programming. It’s one of the very first things you’ll do when learning how to program a new microcontroller.…
If you’re looking for a beginner-friendly way to get into sensing the physical world with Arduino, ultrasonic distance measurement is a fantastic place to start. In this project, we’ll use an HC-SR04 ultrasonic sensor to measure how far away an…
If you’ve already built a basic servo project and you’re ready for the next step, this one’s for you. In this project, we’re going to control two servo motors using two potentiometers, and on top of that, we’ll display their…
Have you ever wanted to move something smoothly with your hand and see it come to life using a servo motor? Whether you’re building a robotic arm, a remote-controlled car, or just exploring electronics, learning how to control a servo…
