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

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

The Digg Button from adafruit industries www.adafruit.com is a very simple DIY electronics kit suitable for beginners. It consists of a microprocessor, a 3-digit display, a button and some available i/o pins. As it comes from adafruit, it’s a counter that displays the number of times it’s button has been pressed. The open i/o lines

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

I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable, I’ve had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to

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
English version available at the bottom Se enseñara paso a paso como instalar los controladores (drivers) necesarios para el correcto funcionamiento del programador USBasp para microcontroladores AVR. Primero, mencionaremos algunas consideraciones para evitar fallos por usos indebidos del programador. También se mencionará el protocolo y pines que debe tener en cuenta para poder programar su
This instructable will show you how to read the number on a binary pushwheel or thumbwheel switch using LED’s or an AVR microcontroller (I’m using an ATmega328p but this can be adapted for any AVR or probably another microcontroller of your choice). Multiple thumbwheel switches can be strung together to make an electronic combination lock,
The Arduino — and AVRs in general — have a wide range of power supply options ranging from around 1.8V to 5.5V. The choice of voltage is usually determined by the desired clock speed or power consumption requirements. The Arduino and its many variants have power jacks that allow connections from big, clunky “wall warts.”
