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 ...

Computer monitors often include one or more LED indicator lights that show these devices' operating status. Monitor manufacturers can build a set of signals -- made up of sequences of LED flashes and ...

Blinking an LED is generally considered the hardware equivalent of the classic “Hello World” project. It’s a quick and simple test to show that you’ve got the basics worked out, and a launching point ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

An earlier Idea For Design (Hardware-Based LED Blinking Control Eliminates Software Overhead) described a very interesting way to offload the software overhead required for a microcontroller to drive ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...
