IOT application to measure the intensity of light and send feedback

 IOT application to measure the intensity of light and send feedback - Tinker Cad


Tinker Cad Circuit Design:

Light intensity circuit


Components Required:

1) Arduino Uno R3
2) Breadboard Small
3) Led
4) Photoresistor 
5) Multimeter
6) Resistor (x2)


Code for the circuit:

int sensorvalue = 0;

void setup(){
  pinMode(A0, INPUT);
  Serial.begin(9600);
  pinMode(9, OUTPUT);
}

void loop(){
  sensorvalue = analogRead(A0);
  Serial.println(sensorvalue);
  analogWrite(9, map(sensorvalue, 0, 1023, 0, 255));
  delay(100);
}
