A small video showing off the Mindsensors PCF8574A IO expansion board for the Mindstorms NXT.
This little test uses both the input and the output capabilities of this chip.
It was programmed in RobotC. For more details check out http://mightor.wordpress.com
@mwaller98 Yes, it's capable of much more, though. You can use it to read up to 8 buttons. Mindsensors now sells a thing called a magic wand that lets you "write" in the air with the light by waving it around. Just search for "NXT Magic Wand" on YouTube and you'll see some more examples.
