Title: X10 Doc Error?
Post by: chalem61 on May 11, 2010, 02:17 am
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!
