You are correct - the diagram is both confusing
. In addition:
- if it was
correct, it would be so only for the "transmit only" models (TW513/PL513)
- The models that can also receive
(PSC05/TW523) use pin 3 for the receive signal.
- The first line of the tutorial says:
This library enables you to send and receive X10 commands
However the lib does not support Receiving - only sending.
Help us improve the Arduino software, examples, website, documentation, etc.
You'd think you found the best place to post your correction.
I hope you have better luck than I did on the severial occasions when I tried.
It seems that good intentions and posting here do not always (seldom?) get the job done. Until there is an active
system that can address documentation errors, there will always be frustration for those impacted by the error. This is a pity since it also discourages those that only want to help make things better.
