The Wiring code in this recipe is really straightforward.
Wiring waits for a command to come from the serial port. When it gets a command (1, 2, 3 or 4) it “presses” the relevant button on the remote control.
Note that when we pass a command to move sideways, the Wiring code “presses” two buttons at once: the left or right button to turn the wheels and the forward button to move (just like the gas pedal in a real car).

Wiring concepts in this recipe:
Activating digital pins from Flash

serial communication (input)

BEFORE YOU START, connect the USB cable to the Wiring board and your computer.

Working with the Wiring code of this recipe
Bridge page ‘For more detailed instructions, see the “Export Wiring Code Guide”‘
Click inside the text box bellow, select the entire code content (use the ‘Select All’ command) and copy
Open the Wiring environment and create a new “Sketch” (File > New)

Paste the code into the new Sketch
Verify the code (Sketch > Verify)
Reset the Wiring board
Export the code to the Wiring board (File > Export to Board)
Wait for the “Success” message; then reset the Wiring board again

If you get an error, make sure that the XML broker is NOT running.

Bridge page: If after quitting the Broker you still are not able to export the code, see the “Wiring Errors Guide”
