Then its use less during the fast paced matches.

I'd love for there to be an inexpensive I2C color sensor, but all the ones I can find are serial.

The cRIO has a serial port, as does an arduino

Wouldn't serial limit us to one color sensor? Or can multiple sensors be on the same serial line?
If we connected an arduino to a color sensor via serial, what would we use to connect the color sensor to the robot? Analog?

Could we use three phototransistors instead?
