I'm not 100 % sure where you would add this in.....so I took a guess....
attached is my entire code so far....
the schematic and picture is posted...I replaced resistors with 33 K's now instead of 10 K's....
I have an electrolytic 10 uF cap on each device and a .01 u F ceramic cap on each (I was hoping that could work)
disregard the email tonight.....
I'm going to take a video tonight of it working so far.....so you'll have a better image...
attached is the code so far....with a few updates you gave me....
