When I ran across the Jar of Fireflies Instructable sometime this past summer, I knew I had to build it. Full credit to Keso for an excellent set of instructions! I wouldn’t have gotten to the point of developing the firefly behavior without such a solid base for building the hardware, as well as firmware to start it […]

Last year I modified a blue LED fan with RGB LED’s to enhance the look of my server case. Last summer I built a gaming computer and ever since I wanted to light it up with multiple controlled lights and fans. I finally figured out an easy interface and designed a simple network (the “fan

Microcontrollers (MCUs) are fantastic little ICs that give an extra element of versatility to your electronics, robotics or other project. But they’re really not much use on their own. To function, all MCUs need some sort of support components, and a board to live on — one example of course being the famous Arduino. These

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

This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and

Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? No need to buy or make inconvenient HV programmer only for unlock couple of Tiny AVR’s. This Attiny fusebit HV doctor will cure your dead tiny microcontrollers, by restoring all fusebits to factory settings – nice and

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
