/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...
JSON.parse与eval和能将一个字符串解析成一个JSON对象，但还是有挺大区别。
JSON在云计算和互联网领域广泛应用,用于数据传输和存储。 在Arduino开发中,可以使用Arduino JSON库来解析和生成JSON数据。Json.Parse是JSON库中的一个函数,用于将JSON字符串解析为JSON对象。然而,当Json.Parse返回意外的JSON输入时,可能是由于以下原因: JSON格式错误:JSON字符串可能不符合JSON语法规范,如缺少引号、...

首先更改serial物件內arduino所對應的com port編碼(例如將COM2改成COM3),接著按下metro物件上的開關便可以看到最下方的六個數字訊號瘋狂地跳動了。 打開metro上的開關能夠連續觸發送出r a訊號,使Max/MSP不停去讀取(read)類比(analog)的各腳位數值;下方asciimessage2max物件此時會連續送出如a 1 2 3 4 5 6般...
