Sorry for being a noob.
So how many gyroscopes could I have on a Arduino Mega 2560?
Wait, I think I get is now. I can connect the sensors in parallel along the same wires like this: (not really parallel but you get what i mean)
(Taken from: Get on the BlinkM Bus with a BlinkM Cylon – todbot blog )
Then I can get the data from each sensor as long as they have a unique address.
Am I correct?
