Electric car alarm based on Orange Piede

Electric car alarm based on Orange Piede

1 Overview

This small project is implemented based on the Orange Pi IO port to output high and low levels; the hardware modules used include Orange Pi, relays, 433M wireless modules, vibration sensors, and speakers.

3. Summarize

This small project is a small project done in the process of learning Orange Pie. I am looking for some fun in the process of learning; I hope everyone can give me corrections.
