I am currently working on a PIR alarm system that senses motion and relays that info with a 433MHZ transmitter to a receiver that has a buzzer and LED. I have managed to get that working but I recently bought a GSM shield and want to combine a code that I found online but I seem to have run into some trouble. I want to receive a SMS when motion is detected as well as send the information wirelessly to my RX circuit. I keep getting error messages and I have searched the forums and google for help but to no avail. If someone can point me to the right direction or possibly help me merge the codes that would be amazing. Thank you
// Include VirtualWire library
#include <VirtualWire.h>
int led_pin = 13;
int transmit_pin = 12;
int pir_pin = 2;
int val = 0;
int pir_state = LOW;
void setup()
{
Serial.begin(9600);
vw_set_tx_pin(transmit_pin);
vw_setup(4000); // Transmission rate
pinMode(led_pin, OUTPUT);
pinMode(pir_pin,INPUT);
}
void loop()
{
char msg[1] = {'0'};
// Get sensor value
val = digitalRead(pir_pin);
// Change message if motion is detected
if (val == 1)
{
msg[0] = '1';
digitalWrite(led_pin, HIGH); // Flash a light to show transmitting
vw_send((uint8_t *)msg, 1);
vw_wait_tx(); // Wait until the whole message is gone
if (pir_state == LOW)
{
Serial.println("Motion detected!");
pir_state = HIGH;
}
}

Sorry I am going to post the error messages soon. I accidentally posted the same code twice. Here is the GSM code I'm trying to merge with the above code

GSM_SMS sms;
// char array of the telephone number to send SMS
// change the number 1-212-555-1212 to a number
// you have access to
char remoteNumber[20]= "1-212-555-1212";
// char array of the message
char txtMsg[200]="Love You *ARDUINO*";
