Introduction

This experiment demonstrates how to interface the ESP32 with I2C sensors, such as an MPU6050 accelerometer or a BME280 temperature and humidity sensor.

Materials Required

• ESP32 Development Board
• I2C Sensor (e.g., MPU6050, BME280)
• Pull-up Resistors (4.7kΩ for I2C lines)
• Breadboard and jumper wires
• Arduino IDE

Circuit Diagram

The following diagram shows how to connect an I2C sensor to the ESP32:

Steps for the Experiment

1. Connect the I2C sensor to the ESP32 according to the circuit diagram.
2. Write a program to read data from the sensor over I2C.
3. Upload the program to the ESP32 and open the Serial Monitor to view the sensor data.

Explanation

The ESP32 communicates with I2C sensors over the I2C protocol, allowing it to read sensor data with minimal wiring. The sensor's data can be used for various purposes, such as monitoring temperature, humidity, or motion.

Results and Observations

• The sensor data (e.g., temperature, humidity, or accelerometer readings) should appear in the Serial Monitor.
