Pinout Explanation
The 12V Mini Ambulance Siren is a compact and powerful siren module designed for various IoT applications, including security systems, alarm devices, and automotive projects. The module features a simple pinout structure, making it easy to integrate into your projects.
Pin Description
Here's a breakdown of each pin on the 12V Mini Ambulance Siren module:
1. VCC (Red Wire)
Function: Power supply pin
Voltage: 12V DC
Description: Connect this pin to a 12V DC power source to power the siren module.
2. GND (Black Wire)
Function: Ground pin
Voltage: 0V
Description: Connect this pin to a GND (ground) point in your circuit to complete the power supply connection.
3. TRIG (Trigger) Pin (Yellow Wire)
Function: Trigger input pin
Voltage: 3.3V to 5V DC (TTL level)
Description: This pin is used to trigger the siren module. When the TRIG pin is pulled high (3.3V to 5V DC), the siren will sound. When the TRIG pin is pulled low (0V), the siren will stop.
4. NC (No Connection) Pin (White Wire)
Function: No internal connection
Voltage: N/A
Description: This pin is not connected to any internal circuitry and should not be used.
Connection Structure
To connect the 12V Mini Ambulance Siren module to your project, follow these steps:
1. Power Connection
Connect the VCC (Red Wire) pin to a 12V DC power source.
Connect the GND (Black Wire) pin to a GND (ground) point in your circuit.
2. Trigger Connection
Connect the TRIG (Trigger) Pin (Yellow Wire) to a digital output pin on your microcontroller or control device.
When the TRIG pin is pulled high (3.3V to 5V DC), the siren will sound.
When the TRIG pin is pulled low (0V), the siren will stop.
Important Notes
Make sure to connect the VCC and GND pins correctly to avoid damaging the module.
The TRIG pin is a digital input and should be driven by a signal with a TTL level (3.3V to 5V DC).
The siren module can be loud, so ensure you use proper sound-level protection measures when testing or operating the module.
By following these instructions, you can easily integrate the 12V Mini Ambulance Siren module into your IoT project and add an audible alarm feature.

Overview

The 12V Mini Ambulance Siren is a compact, high-decibel siren designed for use in IoT projects, robotics, and other applications where a loud, attention-grabbing alarm is required. This siren operates on a 12V DC power supply and is compatible with a wide range of microcontrollers and development boards.

Technical Specifications

Operating Voltage: 12V DC
 Current Consumption: 500mA
 Sound Pressure Level: 120dB
 Frequency: 2.5 kHz
 Dimensions: 40mm x 30mm x 20mm
 Weight: 50g

Pinout

The 12V Mini Ambulance Siren has two terminals:

Positive (Red Wire): Connect to 12V DC power supply
 Negative (Black Wire): Connect to Ground (GND)

Code Examples

### Example 1: Using the 12V Mini Ambulance Siren with Arduino

In this example, we will use an Arduino Uno board to control the 12V Mini Ambulance Siren.

Hardware Requirements

Arduino Uno board
 12V Mini Ambulance Siren
 12V DC power supply
 Jumper wires

Code
```c++
const int sirenPin = 2;  // Digital pin 2 is used to control the siren

void setup() {
  pinMode(sirenPin, OUTPUT);
}

void loop() {
  // Turn on the siren for 2 seconds
  digitalWrite(sirenPin, HIGH);
  delay(2000);
  
  // Turn off the siren
  digitalWrite(sirenPin, LOW);
  delay(1000);
}
```
In this example, we use digital pin 2 to control the siren. When the pin is set HIGH, the siren turns on, and when it is set LOW, the siren turns off. The `delay()` function is used to create a 2-second on/off cycle.

### Example 2: Using the 12V Mini Ambulance Siren with Raspberry Pi (Python)

In this example, we will use a Raspberry Pi board to control the 12V Mini Ambulance Siren using Python.

Hardware Requirements

Raspberry Pi board
 12V Mini Ambulance Siren
 12V DC power supply
 Jumper wires

Code
```python
import RPi.GPIO as GPIO
import time

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Set up the siren pin as an output
siren_pin = 17
GPIO.setup(siren_pin, GPIO.OUT)

try:
    while True:
        # Turn on the siren for 2 seconds
        GPIO.output(siren_pin, GPIO.HIGH)
        time.sleep(2)
        
        # Turn off the siren
        GPIO.output(siren_pin, GPIO.LOW)
        time.sleep(1)
except KeyboardInterrupt:
    GPIO.cleanup()
```
In this example, we use the RPi.GPIO library to control the siren. We set up the siren pin as an output and use the `GPIO.output()` function to turn the siren on and off. The `time.sleep()` function is used to create a 2-second on/off cycle.

### Example 3: Using the 12V Mini Ambulance Siren with ESP32 (MicroPython)

In this example, we will use an ESP32 board to control the 12V Mini Ambulance Siren using MicroPython.

Hardware Requirements

ESP32 board
 12V Mini Ambulance Siren
 12V DC power supply
 Jumper wires

Code
```python
import machine
import time

# Set up the siren pin as an output
siren_pin = machine.Pin(32, machine.Pin.OUT)

while True:
    # Turn on the siren for 2 seconds
    siren_pin.value(1)
    time.sleep(2)
    
    # Turn off the siren
    siren_pin.value(0)
    time.sleep(1)
```
In this example, we use the `machine` module to control the siren. We set up the siren pin as an output and use the `value()` function to turn the siren on and off. The `time.sleep()` function is used to create a 2-second on/off cycle.

Note: In all examples, ensure that the 12V Mini Ambulance Siren is properly connected to the 12V DC power supply and the microcontroller or development board.
