The LilyPad Bee is a radio transceiver that you can sew on to your clothing to create wearables or toy control or anywhere you want you to .The LilyPad Bee supply two power interface, one is 5V and the other is 3.3V,so you have more choices to select power supply .There is a communication interface that you can use to control other devices via serial port(In fact ,the following example code is just tested by this serial port source)

== Features ==

Power supply:3.3V or 5V.If you have a power device who supplies 2V to 6V ,you should connect to “+” not the “3.3V” interface ,if the power is 3.3v you can connect to 3.3V interface directly.
Frequency  :The frequency reaches up to 2.4GHZ
Current Limiting Protection 

== FAQ ==

 Q1:How to judge the LilyPad Bee connect to power exactly?
 A:When the LilyPad Bee connect to power exactly , the “PWR” LED is on and “STATE” LED is flashing;
 Q:How to judge the LilyPad Bee connect to mobile Bluetooth software?
 A:When the LilyPad Bee connect to mobile Bluetooth software ,the “STATE” LED is on not flash.

== Example code ==


=== Instruction: ===

The code tested successfullly by Arduino 1.0 IDE

* BlueTooth module-------Aduino Board
*  Tx0            -------Rx
*  RXI            -------TX
*  GND            -------GND
*  3.3V(+)        -------3.3V(5V)




const int ledPin=13;//pin the led is connected to
int blinkread=0;    //blink rate stored in this variable
void setup()
{
  Serial.begin(9600);//initialize serial port to send and receive at 9600 baud
  pinMode(ledPin,OUTPUT);//set this pin sa output
}
void loop()
{
   blink(); 
}

void serialEvent(void)
{
    while(Serial.available())
    {
      char ch=Serial.read();
      //is this an ascii digit between 0 and 9?the data's type  received from 
      //Mobile phone bluetooth serial port is String tpye
      if(isDigit(ch))
      {
        blinkread=ch-'0';//ascii value converted to numeric value
        blinkread*=100;  //actual rate is 100ms times received digit
      }
    }  
}
//blink the LED with the on and off times determined by blinkrate
void blink()
{
  digitalWrite(ledPin,HIGH);
  delay(blinkread);
  digitalWrite(ledPin,LOW);
  delay(blinkread);
}

== Notes ==

Pin layout is similar but not the same as the pin layout on the Bee. Certain pins have swapped to make sewing easier in projects that use the Arduino ,which has a different pin arrangement from the Bee;
