用户定义功能块(UDFB)之于可编程逻辑控制器就像功能之于微控制器一样。两者都是用于简化代码的结构，使其更容易编写，故障排除和维护。它们也是允许代码在将来被重用的基本结构。 本文引用地址： 本文概述了在Arduino Opta 1中使用的简单UDFB的构造。

The following tutorial will explain how to transform the potential of popular microcontrollers into programmable logic controllers (PLCs). This primer is for those who want to begin learning about ...

For most of our prototype, hobby, or one-off electronics projects it’s perfectly fine to use a development platform like an Arduino Uno or something to that effect. They’re both easy to program and ...

If you're looking to make yourself somewhat more productive on this lazy weekend, and you've got an Arduino or two collecting dust, we've got just the thing to add line after line to your dwindling to ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

Arduino has released Arduino PLC IDE a new version of its IDE (integrated development environment) software for use with PLCs (programmable logic controllers). The software supports the use of Ladder ...

Application control is “via real-time dashboards combined with the Arduino Cloud or third-party services”. Software development is typically Arduino, via Arduino sketches, tutorials and libraries, and ...

Those of you that enjoy building projects using Arduino might be interested in this new Arduino compatible PLC available in three different size, designed by SG-Tronic. Controllino is a ...
