"HELLO"
"5.1 READY"
"Volume: 50"
(mne vypíše aj volume 51, volume 52, volume 51 ale nerobil mi to s týmto programom... zrejme som poslal veľa dát)
dalej su 2 tlačidlá s pullup rezistormi na pinoch D2 a D3
maju funkciu pridávania a uberania hlasitosti, D2 uberá hlas a D3 pridáva hlas.
Je tam nastavený limit do 71 vtedy má vypísať MAX a pri 0 ma napísať MIN.
hovorím fungovalo mi to ale teraz blbne v pohode si ide keď pridávam až do nekonečna, nereaguje na žiadne ifká a pri spustení hneď začne vypisovať bludy...
mam to skontrolované jak programovo tak hardwarovo , všetko premerané preskúšané, akurat nemam dalšie arduino takže si neviem overiť či som skutočne neodpiekol ten convertor alebo niečo, budem rád ak mi niekto ten kód skúsi
...teraz som ho vytiahol ze suflika ale neviem do neho nic nahrat ani nic precitat
