Blink One of the initial Arduino tutorials is Blink, a program that simply turns an LED on and off for one second each. It is a nice demo that doesn't require any external devices and can be written ...

📌 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 ...

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 ...

Once the code is uploaded to the BlinkM, you essentially have a micro Arduino running at 8MHz with a built in LED and 2 I/O lines (5 if you snip off the LED).

Using an Arduino and a little code on your PC, it monitors your screen and creates lighting behind your monitor.

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...
