Pin Configuration

MB35L2 - 35mm Loud Intermittent Buzzer Documentation
Pinout Overview
The MB35L2 buzzer has 2 terminals, which are connected to a microcontroller or a power source to produce an intermittent beep sound. Here's a detailed explanation of each pin:
Pin Structure:
1. Pin 1: Positive Terminal (+)
Function: Connects to the positive voltage supply (VCC) or the output of a microcontroller.
Description: This pin is responsible for providing the positive voltage to the buzzer, which enables it to produce sound.
2. Pin 2: Negative Terminal (-)
Function: Connects to the negative voltage supply (GND) or the ground of a microcontroller.
Description: This pin completes the circuit and returns the current to the power source, allowing the buzzer to function properly.
Connection Guidelines:
To connect the MB35L2 buzzer correctly:
Connect Pin 1 (+) to the positive voltage supply (VCC) or the output of a microcontroller.
Connect Pin 2 (-) to the negative voltage supply (GND) or the ground of a microcontroller.
Important Notes:
Make sure to connect the buzzer to a suitable power source, as excessive voltage can damage the component.
Use a resistor in series with the buzzer if you're driving it directly from a microcontroller output to prevent overheating and ensure proper operation.
The buzzer's operating voltage range is typically between 3V to 28V, with a recommended voltage of 9V or 12V for optimal performance.
Be mindful of the buzzer's current rating and ensure the power source can provide the required current to avoid overheating or damage.
Troubleshooting Tips:
If the buzzer does not produce sound, check the connections and ensure that the power supply is within the recommended voltage range.
If the buzzer is producing a continuous sound instead of an intermittent beep, check the connection to the microcontroller output or the power source to ensure it's not stuck in a high state.
By following these guidelines and connection structures, you'll be able to properly integrate the MB35L2 buzzer into your IoT project and achieve the desired intermittent beep sound.
