📌 Overview This project demonstrates how to use an Arduino Uno to control an LED, making it blink at regular intervals. It's a foundational experiment for learning how to control digital outputs ...

The Arduino Uno has a built-in LED connected to digital pin 13. In this project, we write a basic sketch to turn the LED on and off every second using digitalWrite () and delay ().

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

Learn how to control and blink multiple LEDs using the MAX7219 driver with Arduino. A simple guide for beginners in ...

For the first sketch, let's blink an LED and then extend it to blink multiple LEDs alternately. Before the software part, let's first set up the circuit to connect the LED to the Arduino.

The WatchDuino is exactly what it sounds like, an Arduino-based wrist watch. The component list is short and inexpensive.
