The NXT can also optionally apply 9V to I2C sensors on the same input/wire that is used for reading the analog values. There's a flag to set this up. I know it is accessible in RobotC and I think you should also be able to set it up via NBC. SO (...) (19 years ago, 5-Dec-06, to lugnet.robotics.nxt)
