Circuit Documentation
Summary
This document provides a detailed overview of a circuit that includes an Arduino UNO as the central microcontroller, interfaced with various sensors and modules including an MPU-6050 motion sensor, a GPS NEO 6M module, an SW-420 vibration sensor, a buzzer, and a 4X4 membrane matrix keypad. The circuit is designed to capture motion data, GPS coordinates, and vibration signals, and provide feedback through a buzzer based on the inputs from these devices.
