Arduino Dual L293B Motor Drive Shield (work in progress,help needed)

Hi folks...

This is my first contribution to the site (kinda contribution, for now) but it's still a work in progress, so I'm not sure if it's ok to post it as a instructable (as I already did).

Anyway, here is the instructable:
https://www.instructables.com/id/Arduino-Dual-L293B-Motor-Drive-Shield-work-in-pro/

I still have few questions and some work to do until we can call it a complete Instructable, so... should I move it here to the Forum?


Thanks in advance,
Rodrigo Fonyat
