Wait a minute!
There is no power source available from the OI. There are a few 10 ma, current limited LED outputs that can be used to drive an LED direct without the use of external resistors. Please see the OI documentation for information on the mapping and pinout for LED drivers. The 5 volt supply that feeds the joystick reference pins is not available for any other use but joysticks. The FIRST rulebook is very clear on this and the IFI documentation as well. Fooling with the joystick power supply comprimises the operation of the OI and how it reads the value of the joystick.
