I have included the Schematics into the source code itself. Here is a Link to the Software of Samay1.
This software is based on a State machine for proper operation and enable the Count down, alarm and proper sleep mode controls.

- Post Video on the operation of the unit.
- Need to make Battery measurement using ADC for alerting when its below the thresholds of operation.
- Check possibility of incorporating a complete RTC showing time on the same hardware.
Let me know your views and ideas on how I can improve on the design as well as the software.
