max serial objects sends data to arduino as ascii bytes. if you simply input integer into serial object, it will become decimal code for the ascii char. 120 in you dummy example would be letter x. you must insert atoi object between data you want to send and serial object. ...

If you want to connect the Arduino to another device using serial communication, you also have to use these two pins. Sending inputs to the computer Open example serialButton, and upload it. The breadboard configuration is the same as in the previous step. Then open the serial monitor: Tool...

arduno语法手册 Arduino的程序可以分为三个主要部分:结构变量变量和常量和函数。 欢迎下载 结构部分 一结构 1.1 setup 1.2 loop 二结构控制 2.1 if 2.2 if.else 2.3 for 2.4交换机c
Serial.pritln("cial"); } 程式的注释就是对代码的解释和说明,编写注释有助于程式设计师(或其他人)了解代码的功能。 Arduino处理器在对程式码进行编译时会忽略注释的部份。 Arduino 语言中的编写注释有两种方式 //单行注释:这整行的文字会被处理器忽略 ...
