Pushbuttons
The shield has space near the pin 13 LED that can be used for two general-purpose
The pushbutton pins are brought out to a series of through-hole pads that you can
connect to other parts of your circuit. One easy way to add user-input pushbuttons to your Arduino is to jumper the
upper pushbutton pin to the neighboring ground pad and connect the lower pushbutton pin to the Arduino or Wixel
I/O line of your choosing (with that line’s internal pull-up enabled). In this configuration, the line is high by default,
and it is driven low when the button is pressed.
Wixel Socket
The shield relies upon a pair of Wixels for its wireless connection. The shield’s Wixel socket allows the Wixel to be
removed and used for other applications.
Note: The above features make the Wixel shield a good general-purpose prototyping board for Wixel
projects. An Arduino is not required to use this board as a Wixel development platform.
1.c. Arduino Pin Usage
The Wixel shield connects to these pins on the Arduino:
• Pin 0 (RX)
• Pin 1 (TX)
• Pin 13 (user LED)
• RESET
• 5V
• GND
The shield uses the Arduino’s 5 V regulator to power the socketed Wixel. It is safe to use this shield in conjunction
with other Arduino shields or electronics that also use these pins, though such electronics could potentially interfere
with the operation of the Wixel shield (and vice versa). For details about the connections, see the Wixel shield for
