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 AVR’s used on this website are …
This music player project built based on AT90USB1286 microcontroller. It uses VS1033D music decoder which integrates music file decoding and digital-to-analog output. Other main part including 16×2 character LCD display, ST7066/HD44780 compatible, using 3.3V instead of 5V and DS1307 real time clock. By finishing this project you can understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and …

Introduction: This is the hardware and source code for an Atmel ATmega48 based four digit Nixie Tube Clock. Description: This was my second Nixie clock project. I wanted something a little smaller / cheaper / simpler then my rather large B-7971 clock. I will post the design for that one of these days. I was …

Morse Code Alarm Clock Modification (Almost) Trivial application of an AT90S2313 or ATtiny2313 in an alarm clock to change the alarm from “BEEP BEEP BEEP BEEP BEEP BEEP BEEP BEEP…” to “WAKE UP” in Morse code. This was designed in response to a request and is in daily use Downloads (Updated 5 December, 2004) AVR Studio …

Based on the Atmel ATtiny12L-4PI microcontroller -A real Time Clock/Calendar for less than US$1.50 in moderate quantity. This is the timekeeping test circuit. It includes a one-transistor circuit to switch in the 5V power supply when present and drop back to the 3v battery the rest of the time. That loop of blue wire-wrapping wire …
If your school, or kids school, or other location relies on a central master clock that is broken, you may have a use for this device. New master clocks are available of course, but school budgets are under extreme pressures, and it really is a satisfying project if you have the necessary skills. This master …

The great adventure that is building clocks continues. Points of interest in this build is that it was the first chance I got to play with the dot matrix display I picked up over winter break, and it’s the first time I’ve soldered and used a surface mount package (albeit I soldered it to a …
