Nixie Clock with AVR using ATmega48 microcontroller

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 trying to simplify everything. And basically wound up with a one chip solution, ... the micro itself ...

AVR assembly language

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 8-bit AVR's, meaning 1 byte (1 byte = 8 bits) width working re ...

AVR digital clock with white seven segment LED display using ATtiny26 microcontroller

This is a digital clock project based on an ATtiny26 microcontroller, displaying time on four seven segment LEDs. The seven segment LEDs glow bright white and are multiplexed through PORTB pins, whereas the segments are driven by PORTA pins. The time is normally shown in hh.mm format but it can be switched to display mm.ss too. The time setting can be done with two push button switches. For more detail: AVR ...

Arduino Powered Binary Clock using ATmega168 microcontroller

This instructable will help you to build an Arduino Binary Clock.  The orignial idea for this instructable was designed by Daniel Andrade.  My instructable uses surface mount components, but can easily be adapted to through-hole components if you wish.  You can follow my other Instructable for Building Your Own Arduino to get started. I would encourage you to give the surface mount an attempt however as thi ...
