+//----------------------------------------------------------------
+// Alarmclock
+// -----------
+// features:
+//  - alarmclock with 2 alarm times
+//  - 128x64 LCD with KS0108
+//  - displays time / time&date / a menu to change time & alarms
+//  - rottary encoder with push button
+//  - relay which switsches on a hi-fi system or something else
+//  - a 1F- Cap as a backup supply
+//----------------------------------------------------------------
+// todo/ desired improvements:
+//  - the sleeptimer isn't integrated already
+//  - a real time clock would be nice
+//  - a speaker or beeper directly connected to the mbed
+//----------------------------------------------------------------
