Introduction
DFRobot Leonardo with Xbee socket is an Arduino Leonardo variant processor.The Arduino Leonardo is
based on the ATmega32u4 chip. It is the latest addition to the Arduino family. Compared with the earlier
Arduino controllers,by using the ATmega32U4 as its sole microcontroller, allows the Leonardo to be cheaper
and simpler to use.Also, because the 32U4 is handling the USB directly, code libraries are available which
allow the board to emulate a computer keyboard, mouse, and more using the USBHID protocol!
Notice:This board is only supported in the latest Arduino IDE 1.0.1 or later version so you will also
need to update the IDE.

Sample Code // # Description: // It is just used to test Leonardo module // Write by Grey // Input "p" once time the led will be turn on;twice to turn off. // It is controled by Serial1 Xbee side only. but you can check the status from serial port. int ledPin=13; int val; int count=0; void setup() { pinMode(ledPin,OUTPUT); Serial.begin(9600); Serial1.begin(115200); // Xbee Serial1 port baud rate should be set the same to the xbee baud rate } void loop() { val=Serial1.read(); // read xbee Serial1 data if(‐1!=val) // "‐1" means no data { if('p'==val){ if(count==0)count=1; else if(count==1)count=0; } if(count==0){ digitalWrite(ledPin,HIGH); // Turn on Serial.println("LED ON"); // you can check the status from serial port. Serial1.println("LED ON"); //you can check the status from serial1 port(xbee). } else if(count==1) { digitalWrite(ledPin,LOW); // Turn off Serial.println("LED OFF"); //you can check the status from serial port. Serial1.println("LED OFF"); //you can check the status from serial1 port(xbee). } } ...
