Ok so i read the article and im trying to get this work but so far i can only get the sensor led to turn on and off im not sure how to get it to turn off and led when its dark around it.
int led1 = 13;
int cath = 2; // negative
int ando = 3; // positive
void setup()
{
pinMode(led1, OUTPUT);
pinMode(cath, OUTPUT);
pinMode(ando, OUTPUT);
Serial.begin(9600);
}
void loop()
{
//TURN SENSOR LED ON
digitalWrite(cath, LOW);
digitalWrite(ando, HIGH);
delay(10);
//REVERSE BIAS
digitalWrite(cath, HIGH);
digitalWrite(ando, LOW);
//READ LED CAP
pinMode(ando, INPUT);
//WRITE TO LED
digitalWrite(led1,digitalRead(ando));
//RESET
pinMode(ando, OUTPUT);
Serial.print("Reset");
}
