In a simple word, Modbus is a language that a device uses to communicate with other devices, software/app, and HMI device. This tutorial is about Arduino, so Arduino represents for the device. By using Modbus, we can make: Two Arduinos talk with each other to control/monitor the output...

Code 代码解析The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup function will only run once, after each powerup or reset of the board.setup()项目开始时调用该函数。用它来初始化变量，引脚模式，开始使用库等。

returnType functionName(parameterType parameterName){ doSomething(); } 引导您完成函数的创建和使用可能更好也更容易。在本练习中,我们将创建一个简单的函数,将两个数字相加。这不是一个特别实用的函数,但是它提供了一个如何创建函数的例子。在Arduino IDE 中创建新的草图。 将草图另存为function_example。 将...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都
