Crash Detection Module Based on MPU6050 and Raspberry Pi Pico

This is a project based on accelerometer to detect and alert the in event of a vehicle crash or accident.

Raspberry Pi Pico

MPU6050 module

Active Buzzer

Breadboard

Solid core wires

Micro USB cable

Do the wiring and note the GPIO pins you are using for later use in writng code
