Hello! I’m trying to connect an Arduino UNO board to a RVR SPHERO and when I upload the code to the RVR this is the output i’m getting. https://imgur.com/uAAISqt
I’ve connected GND, RX AND TX from the Arduino board to the RVR. Do I have to connect anything else?
To make the RVR move, I uploaded the code and connected the three pins, do I have to do anything else?
