Pin Configuration

MB35L - 35mm Loud Continuous Speaker Component Documentation
Pinout Description:
The MB35L speaker component has a total of 4 pins, which are used to connect the speaker to a microcontroller or other compatible devices. Below is a detailed explanation of each pin, along with connection guidelines:
Pin 1: + (Positive Terminal)
Function: Positive voltage supply to the speaker
Connection: Connect to the positive voltage supply (VCC) of the microcontroller or power source (e.g., 3.3V or 5V)
Note: Ensure the voltage supply matches the recommended operating voltage of the speaker
Pin 2: - (Negative Terminal)
Function: Negative voltage supply to the speaker (Ground)
Connection: Connect to the ground (GND) of the microcontroller or power source
Note: Ensure a solid ground connection to prevent noise and hum
Pin 3: IN+ (Input Positive)
Function: Audio signal input (positive phase)
Connection: Connect to the audio output pin of a microcontroller (e.g., DAC or PWM output) or an audio amplifier
Note: The audio signal should be a Pulse Width Modulation (PWM) or Digital-to-Analog Converter (DAC) output, depending on the microcontroller's capabilities
Pin 4: IN- (Input Negative)
Function: Audio signal input (negative phase)
Connection: Connect to the audio output pin of a microcontroller (e.g., DAC or PWM output) or an audio amplifier
Note: Ensure the audio signal is properly phased to avoid signal cancellation or distortion
Connection Structure:
To connect the MB35L speaker component, follow this structure:
Connect Pin 1 (+) to the positive voltage supply (VCC) of the microcontroller or power source
Connect Pin 2 (-) to the ground (GND) of the microcontroller or power source
Connect Pin 3 (IN+) to the audio output pin (positive phase) of the microcontroller or audio amplifier
Connect Pin 4 (IN-) to the audio output pin (negative phase) of the microcontroller or audio amplifier
Additional Notes:
When using the MB35L speaker component, ensure the audio signal is within the recommended operating frequency range (typically 100Hz to 20kHz) to achieve optimal speaker performance.
The MB35L speaker component is designed for continuous operation and can handle a maximum power output of [insert power rating]. Ensure the power supply can handle the maximum current draw of the speaker.
For proper audio signal transmission, use a suitable audio cable or PCB traces to connect the audio output pins of the microcontroller or audio amplifier to the MB35L speaker component.
By following these guidelines, you can successfully connect and utilize the MB35L speaker component in your IoT project.

Pinout

The MB35L has two pins:

Positive (VCC): connect to the positive terminal of the power source
 Negative (GND): connect to the negative terminal of the power source

Code Examples

### Example 1: Simple Buzzer Control using Arduino

In this example, we will connect the MB35L to an Arduino board and control it using a digital output pin.

```c++
const int buzzerPin = 2; // Pin 2 for the buzzer

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

void loop() {
  // Turn on the buzzer for 1 second
  digitalWrite(buzzerPin, HIGH);
  delay(1000);

// Turn off the buzzer for 1 second
  digitalWrite(buzzerPin, LOW);
  delay(1000);
}
```

In this example, we define a digital output pin for the buzzer and use the `digitalWrite()` function to turn it on and off. The `delay()` function is used to create a 1-second on/off cycle.

### Example 2: Using the MB35L with a Raspberry Pi (Python)

In this example, we will connect the MB35L to a Raspberry Pi and control it using Python.

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

GPIO.setmode(GPIO.BCM)
 GPIO.setup(17, GPIO.OUT)  # Pin 17 for the buzzer

while True:
    # Turn on the buzzer for 1 second
    GPIO.output(17, GPIO.HIGH)
    time.sleep(1)

# Turn off the buzzer for 1 second
    GPIO.output(17, GPIO.LOW)
    time.sleep(1)
```

In this example, we use the RPi.GPIO library to control the buzzer. We set the pin mode to output and use the `GPIO.output()` function to turn the buzzer on and off. The `time.sleep()` function is used to create a 1-second on/off cycle.

These examples demonstrate the basic usage of the MB35L continuous loud buzzer in various IoT contexts. By integrating this component into your projects, you can create audible notifications and alerts that grab the user's attention.
