}
}

we are running the above code with results:
j counter: 0 light value: 0

2 out of 3 of our lights are lighting up....
we tried fumbling around with some numbers to see if the LEDs could respond to light intensity and give us variations of values in our results......

can anyone help:
where in the code is it controlling how the light behaves?
aka
why is my LED not acting as a sensor feed?

THANKS!
