oops sorry I should have explained.. Well really it just doesn't work. when i used the default Serial it did light up the LED on pin 13 upon entering the following text
"1 1 1 1 1 1 1 1 1 1 1 1 1" followed by Enter. However as soon as i switch the Serial to Serial1. nothing happens. I can enter a million "1 1 1" followed by enter but the LED does not light up. I hope i have explained myself well. if you need any further details please do let me know

Thanks
