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 [...]

ScoreTime is a digital wall clock with a bonus inside: an infrared remote-controlled scorekeeper. The hardware is based on the Atmel AVR microcontrollers: an ATmega48 in the base, and ATtiny28 in the remote. ScoreTime helps players keep accurate score and track who is the current player in addition to performing its duties as a [...]

The project shows you how to build digital clock based on microcontroller ATtiny2313. The time is displayed in the format “hh: mm: ss” on the alphanumeric display LCD of size 16 x 2 with driver HD44780. The 16 bit internal counters interrupts of MCU is used to generate time (1 interupt = 1 second). The [...]

I’m sure that everyone has alarm clock in their house from the simple to the elaborate, to help them get a start on the day. But you need to be there to set it. DJ Delorie has design Multifunctional Alarm Clock that has three primary features: automatic time setting on power-up, remote management and streaming [...]
