To get better UV expose, Andrianakis has built new Switch Timer that will turn of his UV exposure box after some time. The timer uses ATmega8 as main processor and two 7-segments LED as display. There are two buttons for set and start the timer. When time runs out, microcontroller switches relay and also sounds […]

This stand-alone internet wireless music player, named as Wireless MP3 (WMP3), uses Atmel AVR AT90CAN128 microcontroller as main ‘brain’. The device can play music from internet radio stations like Shoutcast (www.shoutcast.com), connect to shared network drives and play mp3 files. Ubiquitous 802.11b wireless link is used to connect to the internet. “WMP3 uses HTTP protocol […]

What is an AVR ? First of all AVR stands for: Advanced Virtual RISC. The founders are Alf Egil Bogen Vegard Wollan RISC (also forms AVR). An AVR is a small microcontroller (chip, IC) which is switching digitally (controller) by means of so called i/o’s (input/output pins) The i/o’s do all the digital switching. The […]

The IOSTRING is a modular physical user interface system which consists of a series of three basic board modules designed around the Atmel AVR AtMega88 MCU. Each module type can handle switches, pushbuttons, rotary selector switches, rotary shaft encoders, potentiometers, LED’s, LCD displays, and an alphanumeric LED display. Dual footprints are provided on each board […]

Switching between Red, Green and Blue (or Blue1 or/and Blue2 for an RGBB type): An RGB LED is a LED which has three (or four for an RGBB type) semi-conductor LED’s in one normal housing i.e. standard 5 mm. The Red LED is made of Gallium Arsenide Phosphide on Gallium Phosphide, the Green LED is […]
