I don't get it. This seems like such an easy fix but I can't spot the compiling problem. The code below.

If I comment out the line:
LDR_Value = analogRead(LDR_PIN);
It'll compiles so it's gotta be a problem solely with that line.
The error is:
TLC5940_10leds_demo.cpp: In function 'void loop()':
TLC5940_10leds_demo:114: error: expected )' before ';' token TLC5940_10leds_demo:114: error: expected primary-expression before ')' token TLC5940_10leds_demo:114: error: expected ;' before ')' token
I copied that line from another sketch where it compiles without a problem. I just can't see it. - Scotty
