Control sprite with arduino

#1

Hello all,
I would like to know if there is a method to be able to control a sprite on mBlock 3 with arduino, I tried serial coomunication but it did not work.
I know that there is a “Broadcast” extension on mBlock 5, but I couldn’t find an equivalent on mBlock 3, while waiting for mBlock 5 to be able to manage also arduino Nano
Best regards
