Arduino/Bluefruit tester code for photoresistor

Bluefruit_Tester

// This code tests your photoresistor and prints the value to the serial port to make sure your arduino is hooked up correctly
// to test with BlueFruit Ez-Link run code onto ardunio with it plugged into computer with USB port first & check you are getting input from your sensor with it plugged in
// Then unplug the arduino from the computer and change the input for the sketch by going to 
// Tools > Serial Port > /dev/cu/adafruit....nameOfBlueTooth
// then open the serial monitor and you will be able to see the input from your sensor wirelessly!!!

int lightPin = 0;  //define a pin for Photo resistor change this if your photosensor is in another analogue Pin


void setup()
{
    Serial.begin(9600);  //Begin serial communcation
    
}

void loop()
{
   
  Serial.print(analogRead(lightPin)); // print the value from the photo sensor 
  delay(100);
   
}
