Arduino Quang trở LDR (Light-dependent resistor)

Arduino Quang trở LDR (Light-dependent resistor)

Proteus:

Arduino IDE:

int quangtro = A4;

void setup() {

  // put your setup code here, to run once:

  Serial.begin(9600);

}

void loop() {

  // put your main code here, to run repeatedly:

  int giatriquangtro = analogRead(quangtro);

  Serial.println(giatriquangtro);

  delay(500);

}
