Vreau sa comand variatorul de tensiune pentru becuri cu incandescenta cu telefonul, nu doar din taste sau cu telecomanda in infrarosu, cum am prezentat in articolul Variator de tensiune pentru bec cu Arduino (VI). Pana la asta, m-am gandit sa conectez un afisaj LCD1602 (16x2) la Arduino si sa vad ce caracter este transmis, in cad ca gasesc o aplicatie in care sunt butoane si nu am "legenda".
Schema de conectare folosita este:
iar sketch-ul de testare este:

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.

Am revenit la partea de variator de tensiune pentru bec cu incandescenta,pana nu dispar de tot de pe piata... de data asta am pus si un afisaj LCD alfanumeric 1602 (16 coloane si 2 randuri), 2 butoane fara retinere pentru creste si scadere intensitate luminoasa si 16 trepte ... Partea cea mai complicata si cea mai periculoasa, care detecteaza trecerea prin zero a tensiunii retelei si, care comanda triacul, se gaseste in articolul Variator de tensiune pentru bec folosind un Arduino:
Eu am conectat si afisajul LCD la pinii 8..13 obtinand:
- bec stins (0%):
- treapta 1 (6%):
- treapta 2-a (13%):
- treapta 3-a (19%):
- treapta 4-a (25%):
- treapta 5-a (31%):
- treapta 6-a (38%):
- treapta 7-a (44%):
- treapta 8-a (50%):
- treapta 9-a (57%):
- treapta 10-a (63%):
- treapta 11-a (69%):
- treapta 12-a (75%):
- treapta 13-a (82%):
- treapta 14-a (88%):
- treapta 15-a (94%):
- treapta 16-a (100%), adica maxim:
