Lähemalt seadme südamest..

Et kõik oleks kenasti ühes kohas, siis teen siin ka lühikese ülevaate kasutatavast mikroprotsessorist/kontrollerplaadist. Selleks on ühe Poola firma MikroVega toodang ATmega128 chipiga kontroller, millele on integreeritud juba max232, RTC ja igasugused muud kellad ja viled.
