As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...

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 ...

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.

Congratulations, you’ve now gotten you’re Arduino powered and running the Blink program that is flashing the LED. Next thing you need to do is install the Arduino Integrated Development ...

To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based LedControl library makes programming the spedometer a snap.

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 ...
