 Sparrow is an excellent platform for IoT, ultra low-power wireless computing and energy harvesting, with state-of-the-art sensing capabilities. It was designed to work with a range of wireless protocols, including IEEE 802.15.4, 6LoWPAN and ZigBee. Sparrow is an excellent platform for IoT, ultra low-power wireless computing and energy harvesting, with state-of-the-art sensing capabilities.

 +===== Radio Transmission =====
 +
 +We will use the [[https://code.google.com/p/zigduino-radio/|ZigduinoRadio]] library in order to send data between two or more Sparrow nodes. You can download the library from {{::zigduinoradio_201111130010.zip|here}}.
 +
 +Here's an example code: 
 +
 +<code C>
 +/*
 + 
 +Run this sketch on two Zigduinos, open the serial monitor at 9600 baud, and type in stuff
 +Watch the Rx Zigduino output what you've input into the serial port of the Tx Zigduino

 +#include <ZigduinoRadio.h>
 + 
 +void setup()
 +{
 +  ZigduinoRadio.begin(11);
 +  Serial.begin(9600);
 + 
 +  ZigduinoRadio.attachError(errHandle);
 +  ZigduinoRadio.attachTxDone(onXmitDone);
 +}
 + 
 +void loop()
 +{
 +  if (Serial.available())
 +  {
 +    ZigduinoRadio.beginTransmission();
 + 
 +    Serial.println();
 +    Serial.print("Tx: ");
 + 
 +    while(Serial.available())
