This is the sensor base shield of Linker kit. It can accept the connection of various modules of LinkNode. This shield can be used with Arduino,pcDuino,Arduino 101 etc.

== Features ==

*14 Digital connectors(D0-D13)

*6 Analog connector (A0-A5)

*1 I2C sockets (A4,A5) 

*1 SPI socket (D10-D13)

*1 Software SPI socket (D7-D4)

*2 UART connectors (D0、D1)

*1 Reset button

*Compatible with all LinkNode modules

'''Note:I2C via connect to A4 ,A5 by default,if these pins not adapt to your boards, you can choose the welding points behind the welding board.'''

Code:

 int  beep = 1 ;
  void setup() 
  {
    pinMode(beep, OUTPUT);    
  }
  // the loop function runs over and over again forever
  void loop() 
  {
    digitalWrite(led, LOW);                                    
    delay(1);                      
    digitalWrite(led, HIGH); 
    delay(1);
  }   

=== 2. More sensors ===
