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…
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…
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…
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,…
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…
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…
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…
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…
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…
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…
