This project shows you how to store data into microSD card in files with FAT32 format using microcontroller AVR ATmega32. The MCU receives sensor’s data through internal ADC. You can connect up to 8 different sensors to the system.

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, [...]

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 [...]

In this video tutorial, nerdkits show you how to use the timer interrupts on an ATMega168 chip to make a simple timer. It is possible to make your own reasonably accurate alarm clock, create systems to perform timed automated tasks, or create a multitude of other projects with real time clock in AVR.
