Keeping time with the ATMega Desk Clock

The Time Desk Clock – powered by Atmel’s versatile ATMega MCU – is a DIY soldering kit now available on Adafruit’s website.

Designed by the SpikenzieLabs crew, the kit features extra digital and analog pins (broken-out), an open serial port and I2C (all easily accessible within the case), as well as an integrated prototyping area on-board.

The chip arrives pre-programmed, so everything is ready to roll once assembled. Plus, the downloadable sketch can be modded, with extra hardware added for an extra level of customization.

Required tools and supplies for putting the kit together? Soldering iron, screwdriver, flush cutters and fine sand paper.

Key features include:

  • Easy through hole soldering kit
  • Back-up battery for clock
  • Time, month, day and date
  • Alarm with buzzer
  • Re-program with the Arduino IDE
  • Free digital I/O pins 4 (of which 2 are used for Serial)
  • Free analog input pins 2
  • All pins broken in a convenient header
  • Two sets of PCB mounting holes
  • Optional “break-off” mounting holes
