Basically, you want to build a dongle to simulate autonomous mode for code testing. Yes, during the competition, the field controls autonomous, but you need the dongle to test out your code (if any) prior to getting there. It can be built with $5.00 of parts. It is VERY USEFUL to have. Do the right thing and build it. Do not forget the disable switch either. You never know when your code registers may carry over and find you robot going backwards at maximum speed when you least expect it.
