This is a simply and easy build 4-channel timer, suitable for energy saving, simple hardware and nice firmware with c coding. Automatic power down mode, simple settings, optional buzzer for sound alarm.This project use ATMEL AT89C4051 and MAX7219 as the main parts.[more]

As we know a POV is very popular project and this is a cool POV that made for Bicycle.This project consist of 48 LEDs total, 24 on each side of the board. This gives higher resolution patterns, and they can be seen from both sides of the bike. The LEDs are controlled from a series of 74×373 ICs connected to an 8 bit bus on the microcontroller.

As opposed to shift registers, all 48 LEDs can be updated in 20-30 microcontroller cycles, leaving plenty of time to spare to figure out what should go there.This project use ATMEL ATTiny861.[more]

This project will create a rolling display pattern using up to 8 Light Emiting Diodes. But more importantly, this page demonstrates how to set up and run a basic program using the power ATMEL AVR development kit.ย�This guide will explain the AVR instruction on a line-by-line basis for the best clarity.[more]

The USB-Servo is a device to control a servo via USB. A servo is a motorized device that is commonly used in remote controlled cars and planes.This project use Atmel AVR to interface to USB.[more]

SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs).[more]
