In Arduino 2&3 are default tx,rx pin redeclaring same pin using softserial wont work
int timesTosend=1;
int count=0;
String phone_no="+9036768091";
void setup()
{
Serial.begin(9600);
mySerial.begin(9600);//Open Serial connection at baud 9600
delay(2000);
Serial.println("AT+CMGF=1"); //set GSM to text mode
delay(200);
}
void loop()
{
while(count<=timesTosend)
{
delay(1500);
Serial.print("AT+CMGS=" + phone_no);
Serial.print(char(13)); //Enter command
delay(100);
Serial.print("It works!"); //SMS body
Serial.write(0x1A); // sends ctrl+z end of message
delay(500);
Serial.write(0x0D); // Carriage Return in Hex
Serial.write(0x0A); // Line feed in Hex
//The 0D0A pair of characters is the signal for the end of a line and beginning of another.
delay(5000);
count++;
}
}
use this code if u r connecting gsm to 2&3..............
if u r going to use any other pin then use softserial method
example:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(4,5);
