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.

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape.

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 ...

Because the Arduino is executing the pre-installed software called Blink. Congratulations, you’ve now gotten you’re Arduino powered and running the Blink program that is flashing the LED.

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 ...

CodeBender is a browser-based IDE that supports uploading to nearly any Arduino board. You can use the program to copy sample code, browse code uploaded by other users, and even store private ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...
