Here is my code:

#include “SIM900.h”
#include “sms.h”
SMSGSM sms;
int numdata;
boolean started = false;
char smsbuffer[160];
char n[20];
int smsValue;
char sms_position;
char phone_number[20];
char sms_text[100];
int i;

void setup()
{
Serial.begin(19200);
pinMode(12, OUTPUT);
if (gsm.begin(19200))
{
Serial.println("\nstatus=READY");
started = true;
}
else
Serial.println("\nstatus=IDLE");

if (started)
{
for (i = 1; i <= 20; i++)
{
sms.DeleteSMS(i);
}
if (sms.SendSMS("+639954709282", “HELLO THIS IS FEEDOMATIC FEEDING THROUGH SMS IS STARTED”))
{
Serial.println("\nSMS sent OK.");
}
else
{
Serial.println("\nError sending SMS.");
}
}
};

void loop()
{
if (started)
{
sms_position = sms.IsSMSPresent(SMS_UNREAD);
if (sms_position)
{
Serial.print(“SMS postion:”);
Serial.println(sms_position, DEC);
sms.GetSMS(sms_position, phone_number, sms_text, 100);
Serial.println(phone_number);
Serial.println(sms_text);

if (strcmp(sms_text, “on”) == 0) {
digitalWrite(12,HIGH);
delay(100);
}

if (strcmp(sms_text, “off”) == 0) {
digitalWrite(12,LOW);
delay(100);
}
}
delay(2000);
}
}
