video Direction Aware Messaging LED Spin Top We recently built a LED spinning top with message display. Its an improved version of a similar top published by Elektor in their December 2008 issue. The Elektor top can be spun only in one direction. The synchronization required to print message on the LEDs arranged along the […]

With a single LED you can indicate the state of something: on or off. That might be a little boring. With an array of LEDs you can display characters or even some simple blocky graphics. That might add a little pizzaz to a small microcontroller project. You could use individual LEDs wired into a grid

Inspired by various LED Throwies, blinking LEDs and similar instructables I wanted to do my version of an LED controlled by a microcontroller. The idea is to make the LED blinking sequence reprogrammable. This reprogramming can be done with light and shadow, e.g. you could use your flashlight. This is my first instructable, any comments

So you wana learn how to programme a micro controller? This tutorial has been designed as a next step, following the fantastic tutorial ‘Ghetto Programming: Getting started with AVR microprocessor on the cheap.’ by The Real Elliot link you should read this before progressing onto this next step. Today my friends we are going to
This tutorial will step you through the process of creating a set of controllable and configurable traffic lights whilst also teaching you the basics of Arduino. Some knowledge is needed and I highly recommend reading and following through on most if not all of the pages of the following document, created by the wonderful Arduino.cc
