Circuit Documentation
Summary
This circuit integrates various components including sensors (BMP180, MPU-6050), an Arduino Nano microcontroller, LEDs of different colors (red, yellow, blue), a pushbutton, resistors, a piezo buzzer, a micro SD card module, and a 9V battery. The circuit is designed to interface sensors with the Arduino Nano for data acquisition, provide visual indicators through LEDs, receive user input via a pushbutton, and store data on a micro SD card. The piezo buzzer can be used for audio feedback. Power is supplied by the 9V battery, regulated to the required voltages for different components.
