Deoarece, in ultima perioada, am conectat afisajul doar la pinii D2..D7, o sa mut comanda releului de la D7 la D9, cel de-al doilea ramanand pe D8.
Schema de conectare devine:
/* Photocell simple testing sketch.
Connect one end of the photocell to 5V, the other end to Analog 0.
Then connect one end of a 10K resistor from Analog 0 to ground
For more information see http://learn.adafruit.com/photocells
niq_ro adapted software program in 20.01.2014, see http://nicuflorica.blogspot.com/

- lumina orbitoare (soare puternic):
- lumina normala:
- lumina slabuta, s-a aprins un set de lumini, pentru compensare:
- intuneric, s-au aprins ambele circuite de lumini, pentru a compensa lipsa lumnii naturale:
Filmuletul teste cu fotorezistenta, 2 relee si Arduino (II) realizat cu un aparat photo FujiFilm S5700 este de o calitate slabuta, datorita luminii foarte slabe din camera, dar care ajuta la intelegerea modului de comportare al montajului.
