2. Katse -Potentsiomeetri kasutamine-:

Kasutatud:

1 potentsiometer

7 juhtmeid

1 diod

1 rezistor

kood:

int sensorPin = 0;

int ledPin = 13;

int sensorValue = 0;

void setup()

{

pinMode(ledPin, OUTPUT);

Serial.begin(9600);

}

void loop() {

sensorValue = analogRead(sensorPin); // loeb analoog sisendi väärtust ja saadab tagasi täisarvu vahemikus 0 kuni 1023. See tähendab 10 bitilist täpsust (2^10 = 1024).

digitalWrite(ledPin, HIGH);

delay(sensorValue);

digitalWrite(ledPin, LOW);

delay(sensorValue);

float voltage = sensorValue * (5.0 / 1023.0); // konverteerime väärtuse (0 – 1023) ja tagastab (0 – 5V):

Serial.printn(voltage); // Saadud tulemused kirjutame Serial Monitori.
