ESP32 Sensor Project

Overview

This project demonstrates how to use an ESP32 with a basic sensor (the kind often included in Raspberry Pi kits) and a speaker/piezo buzzer.
The ESP32 reads data from the sensor and can also play simple melodies through the speaker.

It includes:

• sensor_distance.ino → Arduino sketch for reading the sensor
• pitches.h & toneMelody.txt → Tone and melody definitions
• layout.png & schematic.png → Wiring and circuit diagrams

Hardware Requirements

You will need:

• An ESP32 development board
• A regular sensor (like the ones found in Raspberry Pi starter kits)
• A speaker / piezo buzzer
• Jumper wires & breadboard

---

Software Requirements

• Arduino IDE
• ESP32 board support (installed through Arduino Boards Manager)

Setup

1. Download or clone this repository.
2. Open sensor_distance.ino in Arduino IDE.
3. Copy pitches.h into the same folder as the sketch.
4. Connect your sensor and speaker following the provided schematic.png or layout.png.
5. Upload the sketch to your ESP32.
6. Open the Serial Monitor to see the sensor readings and hear melodies from the speaker.
