Variator de tensiune pentru bec cu Arduino (VI)

   Am completat variatorul de tensiune in 16 trepte cu 2 butoane si afisaj alfanumeric LCD 16x2 cu un sistem de comanda de la distanta in infrarosu, folosind o telecomanda pentru mp3 player de masina cu codare NEC, pentru a stine, scadea/creste intensitatea si aprinde la maxim un bec cu incandescenta.
   Partea de sketch este o combinatie a celor prezentate in articolele Telecomanda infrarosu HX1838 si Variator de tensiune pentru bec cu Arduino (V):
