Hi
I will give it one more try, on what I am trying to do. It is hard to tell people what I am trying to do.
Here is the setup. Box1 (ping sensor, Arduino, xbee, and resistor led). Box2 (ping sensor, Arduino, xbee, and resistor led). The xbee's are set up as line passing, only.
If both ping sensor's read (distance > 10) then both Led's will be High one Box1 and Box2.
If ping1 sensor read's (distance < 10) and the ping2 sensor read's (distance < 10), Both led's will read low.
If Ping1 sensor read's (distance < 10) and the ping2 sensor read's (distance < 10), Both led's will read low.
