Hi!
First of all, I apologize for my English, I'm from Portugal.
I'm a newbie on Arduino, and I am trying to build a Motorcycle Current Gear Indicator with a 7-segment display, 3 sensors (pedal +; pedal -; Neutral).
I've written this code but my arduino hasn't arrived yet, could you see if the code makes sense for the purpose?
Thank you all
