Send LED HIGH after "x" seconds

Other Hardware LEDs and Multiplexing
5

I added the "wait for 5 seconds" code...thank you Runaway Pancake.

Haven't been able to test it yet because I cannot verify the code with errors.
I don't know how to fix it...I'm still at it, won't give up...and yes, I'm very new at this. :fearful:

Automobile_Deterrent:131: error: a function-definition is not allowed here before '{' token
Automobile_Deterrent:138: error: expected }' at end of input Automobile_Deterrent:138: error: expected }' at end of input
