关于最后一个巨长的代码示例,大部分都是 OLED 的字符定义,挑着看即可。 原文:Easy Motion and Gesture Detection by PIR Sensor & Arduino 在这篇文章中,我们将展示如何使用简单的原件,如红外传感器与 Arduino Nano ,去制作手势检测器。在本文的末尾,你可以学到: 解释红外传感器的应用及其工作原理 使用TPA81 传感...
APIRor Passive Infrared module is really fun to play with. This is what they look like: They are basically a motion detector and are called ‘passive’ in the sense that these devices do not generate any energy for detection purposes. They work entirely by detecting the energy given off by...

The sketch starts with defining the PIR sensor pin and LED pin. I connected them to Arduino pin 2 and 13 (on-board LED). The statement#defineis used to give a name to a constant value. The compiler will replace any references to this constant with the defined value when the program is...
