    Question
    :
    Hi, how about Key1 and SW1. What they do?
    15/05/2014 05:10 PM
    Answer
    :
    KEY1 used to control PWR KEY pin of SIM900A but you can used it as a input.

    #define KEY1 2
    #define KEY2 3

    if( digitalRead(KEY1) == 0 )

    SW1 is the master switch module to control the power supply
