This project focuses on tapping into GM pre-1996 car and light truck diagnostic information. These systems are commonly referred to as OBDI, or ALDL (Assembly Line Diagnostic Link). They are based, in part, on the GM-specific 8192-baud ALDL standard that was used starting in the 1986 model year through 1995. The data stream definitions used […]

This project demonstrates how to build a simple module to read analog sensor and send the data to PC using USB connection. The project uses ATmega48 as main processor and USB FTDI serial-to-usb cable. Simply put header pins on your device which you can plug into providing the microcontroller-computer link. No need for soldering surface-mount

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
