use the Arduino Uno R3 footprint. However, shields can have a different layout depending on the architecture. Stackable PCBs for the Raspberry Pi are referred to as HATs or pHATs while the BeagleBone refers to them as Capes. We'll focus on the Arduino shields throughout this tutorial. ...
adruino uno一块(其他Arduino板子也可,注意引脚就行),面保线若干条,蜂鸣器或小喇叭一个。 原理: 首先讲下简单的乐理知识,知道音乐是怎么演奏出来的自然就可以通过代码来进行编排了。 1.演奏单音符的原理 一首音乐由若干音符组成,每一个音符唯一对应一个频率。如果我们知道了音符相对应的频率,再让 Arduino 按照这个...
