Circuit Documentation

Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller board interfaced with two BME/BMP280 sensors. The Arduino UNO is responsible for managing the sensors and processing their data. The BME/BMP280 sensors are designed to measure environmental parameters such as temperature, humidity, and pressure. The sensors are connected to the Arduino UNO via the I2C communication protocol, utilizing the SDA and SCL lines for data transfer.
