Hi Jessey,

To begin with, here's Dave excellent page on the X10 RF protocol http://www.arkis.net/rf_protocol.htm.

This would give you a pretty good starting point.

The other approach would be to use a CM17A (Firecracker) module; this would eliminate the need for a separate RF transmitter. Theres loads of basic software available to drive it; one such page is at http://www.awce.com/firecracker.htm

Hope this helps!

Regards,

Anand
