课程名称:Node Red 从零开始 - 一天掌握 课程概述: 《Node-Red从零开始》是专为初学者设计的课程,适合那些对Node-Red没有或几乎没有经验的人。Node-Red是一个编程工具,可以将硬件设备、API和在线服务以新颖、有趣的方式连接在一起。该工具提供了一个基于浏览器的流程编辑器,使得用户可以轻松地使用调色板中的各种节点来组合流程,并可以通过单击进行部署。此外,用户还可以在编辑器中使用富文本编辑器创建JavaScript功能,并利用内置库保存有用的功能、模板或流程以供重用。 课程内容还介绍了Node-Red的历史背景,它是由IBM的前沿技术服务团队开发的流式编程工具,现已成为JS基金会的一部分。流式编程是一种描述应用程序行为的方法,能够将应用程序的行为表示为由多个“节点”组成的网络。每个节点有明确定义的功能,可以处理数据并将其传递给下一个节点,形成数据流网络。这种模型非常适合视觉化表示,使得更多用户能够理解流程,而无需深入理解代码的每一行。 Node-Red于2013年初由Nick O'Leary和Dave Conway-Jones作为一项副项目启动,最初用于可视化和操作MQTT主题之间的映射,后来演变为一个通用工具,并于2013年9月开源,至今仍在持续发展,成为JS基金会的创始项目之一。 此外,课程还初步介绍了物联网(IoT)的概念,它指的是全球数十亿个连接到互联网的物理设备,能够收集和共享数据。借助廉价处理器和无线网络,几乎任何东西都可以成为物联网的一部分,赋予设备数字智能,使其能够在没有人为干预的情况下进行通信,数字与物理世界逐渐融合。制造商在产品组件中添加传感器,以便传回它们的性能数据,帮助公司发现潜在的故障,从而避免损坏,同时利用传感器生成的数据提高系统和供应链的效率。 这个课程旨在帮助学生快速入门Node-Red,掌握使用这一工具的基本技能。
Node-Red From Scratch! Node-Red 101 Series From Scratch Node red 1O1 series from scratch is a course designed for beginners who have less or zero experience with Node-Red. What is Node-Red? Node-RED is a programming tool for wiring together hardware devices, APIs, and online services in new and interesting ways. Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the run time in a single click. JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use. Node-Red History Node-RED is a flow-based programming tool, originally developed by IBM's Emerging Technology Services team and now a part of the JS Foundation. Flow-based programming Invented by J. Paul Morrison in the 1970s, flow-based programming is a way of describing an application's behavior as a network of black-boxes, or "nodes" as they are called in Node-RED. Each node has a well-defined purpose; it is given some data, it does something with that data and then it passes that data on. The network is responsible for the flow of data between the nodes. It is a model that lends itself very well to a visual representation and makes it more accessible to a wider range of users. If someone can break down a problem into discrete steps they can look at a flow and get a sense of what it is doing; without having to understand the individual lines of code within each node. Node-RED started life in early 2013 as a side-project by Nick O'Leary and Dave Conway-Jones of IBM's Emerging Technology Services group. What began as a proof-of-concept for visualizing and manipulating mappings between MQTT topics, quickly became a much more general tool that could be easily extended in any direction. It was open-sourced in September 2013 and has been developed in the open ever since, culminating in it being one of the founding projects of the JS Foundation in October 2016. What is IoT? The Internet of Things, or IoT, refers to billions of physical devices around the world that are now connected to the internet, collecting and sharing data. Thanks to cheap processors and wireless networks, it's possible to turn anything, from a pill to an airplane, as part of the IoT. This adds a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate without a human being involved, and merging the digital and physical worlds. Manufacturers are adding sensors to the components of their products so that they can transmit back data about how they are performing. This can help companies spot when a component is likely to fail and to swap it out before it causes damage. Companies can also use the data generated by these sensors to make their systems and their supply chains more efficient because they will have much more accurate data about what's really going on.
