The project purpose is to build an AVR-based website total page hits counter and display it on 7-segments display instead of using only general scripts such as PHP, Java, CGI etc. The counter project consists of three main parts. First, PHP hit counter script run on website. This script will count the number of times [...]

This AVR ATmega128-based VGA controller allows you to visualize images, text, lines and single pixel, on your pc monitor with a 640 x 480 pixels resolution, 64 colors, 60 Hz through USB-serial commands. Besides MCU, it uses FPGA Cyclone with a clock of 27.175 MHz to produce the synchronism signals for the video-vga and the [...]

If you want to build a digital clock with unique features then check out DOTKLOK project. This Arduino-based digital clock can displays a series of unique time-telling animations. The passing of time is displayed with numbers and abstract/geometric patterns taken from classic video games such as Pong, Tetris, Pacman, and Space Invaders. The clock is [...]

The project is used for repairing of broken PC monitors. It can generate video signals with 8 different raster images. The tester features 4 resolutions for each image combination: 640×480×60Hz, 800×600×60Hz, 1024×768×60Hz, and 1280×1024×60Hz. Main component of the project is MCU AVR AtTiny2313 from Atmel running at 20MHz.
