After my very successful glowing orb, I am now ready to commence on my first real project - The Quiz Buzzer.
I need a hint though.
Is there a way for the Ardy to check when one pin goes high before another? (i.e. so I know who pushed their switch first).
(You don't need to write the whole thing for me, just give me a hint to get me started.) 
Regards
