ESP32智能手表 该项目是一个基于ESP32的完全开源的智能手表，该项目正在进行更新，请参阅该项目的hackaday.io页面（ ）。 该项目的目标是创建一个易于重新编程的智能手表，并可以用作物联网控制器或用作DIY时尚声明。 串行通信和充电通过一个微型USB连接器在板上进行，无需任何外部扩展坞。 该手表围绕ESP32 WROOM模块构建，可使用espressif或Arduino IDE进行编程。 使用ESP32可让用户在开发软件的同时，利用可在线获取的开源库和示例进行快速开发。 允许智能手表控制媒体并获取电话通知的配套Android应用程序已拆分为单独的存储库，可以在找到以及使用ESP32进行蓝牙接口的示例草图。 有两种版本的固件可用，V1固件使用深度睡眠以节省电量，并且需要触摸唤醒才能使用。 我不打算对V1版本做任何进一步的工作，但是代码仍然可以使用，因此对于任何想要使用它的人

What is the best way for new Arduino users to get started? I'd say the best way get started with Arduino is to find a workshop near you and see where it takes you. Workshops really accelerate your learning and put you in an environment with like-minded people. I've met all kinds of interesting people through workshops. Sometimes they'll open your eyes to completely new "scenes" that you wouldn't know about otherwise, and other time, you'll find people that might be excited about exactly the same things as you. What is your all-time favorite Arduino project that you've either worked on or heard about from someone else? My own favourite project is the Pen Nib Dress that I made with Steven Tai. It's my favourite purely because it's so beautiful to look at. It's maybe a little impractical (weighing about 5 kg. or just over 11 lbs.) for the poor model who had to wear it but that's the way it is with prototypes! Why do you think Arduino has become such a popular device, especially for tech hobbyists? Arduino is cheap and easy to use, but I don't think that either of these is the main reason that it's so popular. The community around it is what's so remarkable and this is something that you see on the Arduino forums. If they were entirely populated by one group of people, whether it were artists, designers, programmers, engineers or hobbyists, then it wouldn't work, but there seems to be an excellent ecosystem of people on the forum pages to both ask new and challenging questions as well as to answer them. How do you think Arduino has influenced interactive design projects? Arduino has made it possible to quickly and easily get a lot of concepts into the real world. Students can build prototypes that actually work for their final shows and design studios can build the interactive elements of a project themselves without needing an entire technical company to partner with. This allows people to make their ideas a reality, which makes it easier to convey them to a client and also to see if they work the way you expect. I believe that prototyping is an essential process and skill to have in the design industry today and that through this process you will understand more about your project or idea than any number of sketches, renderings or simulations can teach you. Any advice for someone who may be interested in Arduino, but not sure what it's all about? Get Googling! It's all out there on the net: talks, workshops, resources, kits, and more. Once you've seen a few other projects, you'll have an idea of what's possible and what's interesting to you, then you can think about your own projects and how Arduino can help you solve a problem or maybe just create something interesting. What should people expect when they open a copy of Arduino For Dummies? Arduino For Dummies is written for not-technical people that are interested in learning more about technology. The first part of the book gets you familiar with Arduino and what it involves, then there are some simple examples to teach you the fundamentals that you'll need to know before you go further. Later on there's a bit of inspiration to get you thinking about the kind of projects that you can build, a bit of practical advice to get your prototyping skills up to scratch, and then the book dives into a few more advanced uses to give you an idea of what's possible with this fantastic little board!
