what is that bl (second line after main)? I guess bl should be b1.
But then, if b1 gets a 0 from the serial in, how the if-then's will work?

One var is B1 the other is BL, as in bl for bachlight .
I would need to paid more for properly named vars and valid meaningful comments

Well, ok then. BL stands for the back light. But where does it get set?
