Hi,

I have an Arduino board which is programmed to control two motors. I would like to control it externally via a Raspberry Pi Zero board via I2C. I have read in a few places that ROS cannot use I2C and should use SPI. Since I am very very new to ROS, I am asking you guys help to kindly confirm if this is possible. If yes, I will start learning more on ROS and understand everything.

Thanks, Praveen
