Hi All
My Website: http://pachristmas.com
Just thought i would share video of 3 boxes working together.
I just upped the baud to 57600 from 38400 so i can handle up to 8 of these boxes on 1 serial port. (Only building 6 this year.)
What made me really happy is that each box relays the serial to the next and it is doing this via unshielded 18 guage wire transmitting a ttl level signal. Cool.
Most people use RS485 but my yard is small so i thought i would try to get away without it and it worked!
