Arduino cheat sheet

Gavin of Syndey, Australia, wrote in to share his Arduino Cheat Sheet:

Description: I really love cheat sheets. In a lot of cases they can take the place of an entire manual. So I was surprised, given its popularity that I couldn’t find a single-page reference for the arduino online.

I tried to make a sheet that captured all the things I hit the reference for while programming. What data type does the millis() function return? How long till that overflows again? How large can a long get? What baud rates can the serial handle

I’ve managed to cram in every function and bit of syntax for the entire extended reference page on one A4 sheet! As well as some chip specs and other info.
