CODE THIS:
connect two arduino's via a hardwired serial connection (no usb cable) (digital pins 0 and 1)
connect a button and an external LED to each device
pressing the button on one arduino should cause the other arduino's LED to change state (on to off, or off to on)
Button press on one arduino should toggle the state of the LED on the other (on/off) and not keep the LED lit while being pressed
