Schematics:
- single side, single layer trough hole PCB

Source code:
super simple and effective, easy to understand code in assembly language, interrupt based

Hadrware:
1x PIC16f628a MCU is doing all the job via interrupts processing and all the time is in sleep for minimum power consumption, so can work on batteries with months
