Piezo Buzzer

Project Description

This is a simple ESP32 project that uses piezoelectric buzzer to play 262Hz tone.

Hardware Components

• ESP32 DevKit v1
• Piezoelectric buzzer

Circuit Description

The piezo buzzer is connected to the ESP32. The positive pin is connected to pin2, the negative pin to gnd1.

Expected Behavior

When the ESP32 powers up, it should:

1. Set the pin mode as OUTPUT
2. Continuously play 262Hz tone

Success Criteria

The test is successful when:

1. Piezo buzzer runs successfuly

Notes for Implementation

• Use Arduino.h library for arduino core.
• In the loop function, make buzzer play 262Hz tone

Variants

There may be variants with buzzer, GND pin number and the pitch of the sound being played.
