GSM based Vehicle security alarm - Help Programming

Projects Programming
1

Need help (urgent) to figure out a customised version of programming code.

I am working on vehicle security alarm project where vibration sensor will trigger both the siren and start a dialer (phone) which will place call to vehicle owner then vehicle owner will press buttons to cutt off engine etc.

For automatic dialer I m using this youtube tutorial Hacked Phone - Arduino GSM Auto Dialler + Free Schematic and Code - YouTube and for vibration sensor & alarm I am using this youtube tutorial How to Avoid False Positives with a High Sensitivity Piezo Vibration Sensor - YouTube. But facing difficulty in combining both the codes of these two tutorials.

I am sharing the code here for auto mobile dialer:

//Constants That Won't Change
const int call = 11; //Call Button Output
const int back = 10; //Back Button Output
const int keypad7 = 9; //No:7 Button Output
const int alarm_active_led = 8; //Alarm Triggered LED Indicator
const int power_led = 7; //Power OK LED Indicator
const int trigger_input = 6; //Alarm Trigger Input
int repeat =0;

//Variables That Will Change
int trigger_state = 0; //trigger_state = Trigger Input (pin7)

//Setup Routine Runs Once When Reset Is Pressed
void setup() {

//Initialize The Digital Pins As Inputs/ Outputs
pinMode(call, OUTPUT); //Define "Call" pinMode as Output
pinMode(back, OUTPUT); //Define "Back" pinMode as Output
pinMode(keypad7, OUTPUT); //Define "keypad7" pinMode as Output
pinMode(alarm_active_led, OUTPUT); //Define "Alarm LED" pinMode as Output
pinMode(power_led, OUTPUT); //Define "Power LED" pinMode as Output
pinMode(trigger_input, INPUT); //Define "Cancel" pinMode as Input
}

//Loop Runs Indefinately
void loop() {
trigger_state = digitalRead(trigger_input);//Read Trigger Input State

digitalWrite(power_led, HIGH); //Turn Power LED On
digitalWrite(alarm_active_led, LOW); //Turn Alarm LED Off

if (trigger_state == HIGH) { //If Trigger Input HIGH,
//Run Sequence Below 
digitalWrite(alarm_active_led, HIGH);

digitalWrite(back, HIGH); //Press Back Button
delay(100); //Wait 100mS
digitalWrite(back, LOW); //Depress Back Button

delay(100); //Wait 100mS
digitalWrite(back, HIGH); //Press Back Button
delay(100); //Wait 100mS
digitalWrite(back, LOW); //Depress Back Button

delay(100); //Wait 100mS
digitalWrite(keypad7, HIGH); //Press keypad7 Button
delay(100); //Wait 100mS
digitalWrite(keypad7, LOW); //Depress keypad Button

delay(100); //Wait 100mS
digitalWrite(call, HIGH); //Press call Button
delay(100); //Wait 100mS
digitalWrite(call, LOW); //Depress call Button

delay(20000); //Wait 20S
digitalWrite(back, HIGH); //Press back Button
delay(200); //Wait 100mS
digitalWrite(back, LOW); //Depress back Button

digitalWrite(alarm_active_led, HIGH); //Flash Alarm LED
delay(100); //Flash Alarm LED
digitalWrite(alarm_active_led, LOW); //Flash Alarm LED
delay(100); //Flash Alarm LED

while(trigger_state == HIGH){ //If Trigger Input HIGH
trigger_state = digitalRead(trigger_input);//Read Trigger Input State
//Loop Sequence Below
digitalWrite(alarm_active_led, HIGH); //Flash Alarm LED
delay(100); //Flash Alarm LED
digitalWrite(alarm_active_led, LOW); //Flash Alarm LED
delay(100); //Flash Alarm LED
if (trigger_state == LOW) { //If Trigger Input Low
break; //Break
}
digitalWrite(alarm_active_led, HIGH); //Turn Alarm LED On
}
}
}

Code for vibration sensor & alarm:

    }
    delay(100); // wait for current vibration shock to subside
  }
}

void addVibrationSample(long vibrationMillis){
   vibrationEvents[vibrationEventIndex++] = vibrationMillis;
   if(vibrationEventIndex >= VIBRATION_SAMPLE_ARRAY_SIZE){
     vibrationEventIndex = 0; // wrap vibration sample index around when we get to end of sample array
   }
}

"I am facing troubles" is useless information. What kind of troubles?

What does the posted code actually do? How does that differ from what you want?

Dear Paul,
The trouble is I m worried whether this code gets conflict with each other. Though arduino IDE is not giving any error but since I have never combined any code before, I m afraid whether these would work or not. Please look onto the combined code whether it is alright ?

What I think of the code doesn't matter. What the Arduino does when running the code is ALL that matters.

sarfaraz:
which will place call to vehicle owner then vehicle owner will press buttons to cutt off engine etc

Yikes, your building a project that has the capability to shut off the engine !!

Not a good idea to even think of doing that unless you really do know what you are doing.

You dont drive on the roads around by me do you, I am in the UK ?
