First of all hello everyone, my idea is to build a robot using 14 servos and the IO Expansion Shield V5 from DF Robot (IO Expansion Shield For Arduino(V5) (SKU: DFR0088) - Robot Wiki ). Recently i setted up the bluetooth connection between the arduino and my computer initializing every servo except for the ones attached to pins D0 and D1 wich are RX and TX . Until next month i'm not able to buy an arduino due (wich was the original idea) but i'd like to see if i can drive my robot with the leonardo and it's 14 pins.
