Photoresistor

C/C++
Photoresistor has three pins , VCC, GND and OUTPUT
In this project, There are two parts, The Light Emitting Diode or LED circuit and Photoresistor circuit with a LED
THE CONNECTIONS :
For LED circuit (Arduino not needed);
LED(positive) - switch
LED(negative) - Battery(negative)
Switch - Battery(positive)

For Photoresistor;
LED(positive) - pin 13
LED(negative) - GND
Photoresistor(VCC) - 5v pin
Photoresistor(GND) - GND
Photoresistor(Output) - A0

Instead of the LED circuit, I am using a toy LED gun
int led = 13;
void setup() {
  Serial.begin(9600);
  Serial.println("This a virtual gun shooting module");
  Serial.println("Initializing VGSM");
  delay(7000);
  Serial.println("player one ready");
  pinMode(led, OUTPUT);
}


void loop() {
  
  int value = analogRead(A0);
  
  if (value <= 31){
    Serial.println("Player one is down");
    digitalWrite(led, HIGH);
  }
    else {
      Serial.println("Player one is active");
      Serial.println(value);
      delay(150);
      digitalWrite(led, LOW);
    }
  
}
