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

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 ...

This guide will teach you how to run a sample sketch on your Intel® IoT board using the Arduino IDE. These instructions are geared toward the Intel® Edison module with the Arduino* Expansion ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

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 … ...

The Arduino can just increment the counter up to the appropriate LED. The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip.

Instructables user vatosupreme created the effect in the above video by constructing the eyes using ping-pong balls, LEDs, and wooden poles and connecting those LEDs to a control board built with ...

The LEDs blink about four million times per second and (obviously) require the use of a light-receiving handset (sorry for the silly picture – there are no official photos of the LED system yet).

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.
