The Atmel ATTiny85 chip is an 8-pin MCU that is totally awesome. If you’ve been programming with the bigger boys (the ATMega series), these are a nice adventure – you’re rather limited in the number of output pins, but a creative design gives us a lot of flexibility in a very small package. You’ve seen […]

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

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
This is Attiny13 2 channels dimmer with 5 program modes and speed control: 1. Dim between 2 channels 2. Dim 2 channels together 3. Blink mode 1 4. Blink mode 2 5.Blink mode 3 Step 1 Hardware Dimmer is based ot Attiny13V: – 1k flash – 64byte sram – 64byte eeprom – 5 IO pins

Are you bored? Do you want to make something amazing to impress your friends with? Let’s try making an LED cube….. A work of art, that lights up….. Step 1 What in the world is and LED? LED is an acronym for Light Emitting Diode, where electricity can only go one way and when it
This instructable is meant to be a more complete explanation than others available online. Notably, this will provide more hardware explanation than is available in the LED Marquee instructable by led555. Goals This instructable presents the concepts involved with shift registers and high side drivers. By illustrating these concepts with an 8×8 LED matrix I
