ANALOGin put.
JUST TESTING A BASIC THING..int yelPin = 12; //led in digitalpin 12
int s = 3; //analog sensor in analogpin 3
int f =0; //function set on 0 value (=off)
void setup()
{
pinMode(yelPin, OUTPUT); // sets the pins as output
*)pinMode (s, INPUT); //sets the analog sensor as input
*)as seen in Arduino guide, it doesn't have to
been written at all
}
void loop()
{
f=analogRead (s);
if (f >80 ) {
digitalWrite(yelPin,HIGH); //if the sensor's value is bigger than 80,
the LED is on, otherwise it's turned off
}
else {
digitalWrite (yelPin, LOW);
}
}
