2191] Example Applications The Wixel shield for Arduino opens the door for many new Arduino projects. Here are just a few project ideas: • Program, debug/fine-tune, and control your Arduino-based robot without having to touch it. • Stream data from a remote sensor (e.g. your outdoor weather station) to your computer or Arduino. -

Arduinos, and more. Prototyping Space The unused portions of the Wixel shield are configured as general-purpose prototyping space in which you can construct your own circuits. The holes in this prototyping area are connected in a breadboard-like configuration, as indicated by the top silkscreen. - Page 4 Pololu Wixel Shield for Arduino User's Guide © 2001–2013 Pololu Corporation Voltage Dividers The shield has four general-purpose 2/3 voltage dividers that can be accessed by the lower “HV” and “LV” pins (pictured above) located between the Wixel socket pins. These voltage dividers can be used to safely connect 5 V outputs to the Wixel’s 3.3 V inputs: connect the 5 V signal to one of the four HV pins and then connect the...

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 Arduino schematic in Section 1.d. -

With the socketed Wixel but without the extended 1×8 and 1×6 shield headers, the shield itself is 0.8" tall. Since the height of the Wixel and its socket is taller than the typical available clearance between shields, we recommend using the Wixel shield as your Arduino’s top shield. The mounting holes are 1.7" apart and 0.125" in diameter, suitable for #4 screws [http://www.pololu.com/catalog/product/... -

2.e. Using the Arduino Software Using the Arduino software with the Wixel shield for Arduino is not any different than using it normally, except that you will be programming on the COM port associated with a Wixel rather than one associated with your Arduino. In... -

2.f. Writing Sketches for the Wixel Shield Writing sketches for the Wixel shield is as easy as using the standard serial library to transmit and receive serial data. Note that when first enabling the serial port, you might receive an invalid serial byte as a result of noise on the serial lines. - Page 12 Pololu Wixel Shield for Arduino User's Guide © 2001–2013 Pololu Corporation Serial monitor connected to an Arduino running the Wireless Physical Pixel sketch. 2.
