While we're at it, how do I save to files? And is there anything I can do to set up to bricks to do the same thing (like keep track of time and activate a light as an alarm clock), while simultaneously restarting each other in the event of a crashed brick? (For now, the software. Tomorrow, the world-oops, I mean hardware. Yeah, hardware...) OK, this sounds great! While we’re at it, how do I save to files?

The only way you'll really know is if you give it a try :) Good luck with the FTC! It might work if there is only one beacon you’re looking for.

Its kind of inaccurate yes but would it help determine distance? I ask because this year's FTC challenge involves and IR beacon and i would like to know whether this would work as an effective way to determine distance from the beacon. maybe im not thinking right here but what if you were to set the strength value of each of the 5 IR channels as a variable, then compare each variable to a preset scale as in, if channel 3 = 0, beacon is out of range, if channel 3 = 100, beacon is at certain distance.

I have configured the mains frequency correctly. Is anyone facing the same issue with sensing black color with the Hitechnic v2 color sensor?

I prefer to use the MCP23008, it has a lot more functionality. I tend not to use that chip at all anymore. I prefer to use the MCP23008, it has a lot more functionality.

One useful thing about this is that you can set a pin to HIGH and connect a switch between it and GND. If you press the switch... The circiut DOESN'T blow up, and you can read the switch.
