Alarmclock

features:

  • alarmclock with 2 alarm times
  • 128x64 LCD with KS0108
  • displays time / time&date / a menu to change time & alarms
  • sleeptimer, relay is switched of when timer runs out
  • rotary encoder with push button
  • relay which switsches on a hi-fi system or something else
  • a 1F- Cap as a backup supply
