Variator de tensiune pentru bec cu Arduino (VII)

   Dupa cum am scris si in articlul anterior, Smartphone ca telecomanda prin bluetooth pentru Arduino (II), acum am completat partea de variator de tensiune pentru becuri cu incandescenta cu comanda prin bluetooth de pe un telefon cu Android, care era prezentata in articolul Variator de tensiune pentru bec cu Arduino (VI).
   Schemele de conectare sunt combinatia celor 2:

iar modulul notat in schema "AC dimmer unit" are schema:

   Nota: Detalii de realizare a acestuia gasiti in articolul Variator de tensiune pentru bec folosind un Arduino !!!

   Am folosit urmatorul sketch (care nu-i "periat", dar e functional):
