If microcontroler a important for your project, I recommend to put a photo (or a graphic) of a microcontroler near the top of the front page. Otherwise it may be missed.

Hi from Argentina! 100% metric here, except for the water pipes and faucets. I still have nightmares about metric vs imperial screws when I was in a lab a few years ago. Anyway, I expect USA to be a big market for your project and they expect to see everything using the imperial system.
