Try something in the range of 330ohms or so to prevent damage to your board. that, or use pwm. you really should have a current limiting resistor on your LED — (see how bright it gets in your demo video).

should be

pinMode(photoPin,OUTPUT); // set the pin

Hello, I copied and pasted your code above into the IDE and recieve this error:

In function ‘void setup()’:
error: ‘ledPin2′ was not declared in this scope

Do we need to initialize an “ledpin2″ like you did for ledPin?
