arduino g代码解析 包括运动联动 串口数据处理 等功能 仅供参考-arduino g code analysis include motion linkage serial data processing functions for reference

In this simple project, we’ll build a motion-sensing arduino alarm using a PIR (passive infrared) sensor and an Arduino microcontroller. This is a great way to learn the basics of using digital input ( the sensor) and output (in this case, to a noisy
