arduino + sim900 มีบางคนถามมาครับลองเอาไปฝึกเล่นดูนะครับ

เอาไปฝึกลองสั่งเปิดปิดอุปกรณ์ไฟฟ้านะครับ

#include <GSM_Shield.h>
//for enable disable debug rem or not the string       #define DEBUG_PRINT
// definition of instance of GSM class
GSM gsm;



void setup() {
  Serial.begin(9600);
  Serial.println("system startup"); 
  //gsm.InitSerLine(9600);   //initialize serial 1 
  gsm.TurnOn(9600);              //module power on
  //gsm.InitSerLine(9600);   //initialize serial 1 
  gsm.InitParam(PARAM_SET_1);//configure the module  
  gsm.Echo(1);               //enable AT echo 
}


void loop()
{
  
    int reg;
    reg=gsm.CheckRegistration();
    switch (reg){    
      case REG_NOT_REGISTERED:
        Serial.println("not registered");
        break;
      case REG_REGISTERED:
        Serial.println("GSM module is registered");      
        break;
      case REG_NO_RESPONSE:
        Serial.println("GSM doesn't response");
        break;
      case REG_COMM_LINE_BUSY:
        Serial.println("comm line is not free");
        break;
    }
    delay(2000);
    
    reg=gsm.IsRegistered();
      Serial.print("Registration ");
      Serial.println(reg);
    
    delay(50000);
}

อันนี้ก็เป็นอีกตัวอย่างนึงครับ
