• SIM900 AT来电显示开启,一些代码


    /*Note: this code is a demo for how to using gprs shield to send sms message, dial a voice call and 
      send a http request to the website, upload data to pachube.com by TCP connection,
     
      The microcontrollers Digital Pin 7 and hence allow unhindered
      communication with GPRS Shield using SoftSerial Library. 
      IDE: Arduino 1.0 or later
      Replace the following items in the code:
      1.Phone number, don't forget add the country code
      2.Replace the Access Point Name
      3. Replace the Pachube API Key with your personal ones assigned
      to your account at cosm.com
