 Bigger Bigger  Smaller Smaller  Reset Reset

I think there's an error in the schematic on the X10 Tutorial page
arduino.cc/en/Tutorial/X10

The pull-up resistor should be on the "zero-crossing" pin, not on the "data" pin.

I tried hooking things up the way it shows in the picture, and the example program didn't work (my lights didn't blink).

Then I thought about it a bit, and tried putting the resistor on the other pin.  Voila!  Flashing lights!
