2. 

This project is from a  control board (for D on the first picure with letters),  D is RGB LED 5050, WS2812B ring panel (1 ring, 15 RGB LEDs).

Its control board is pixelblaze v2 is from electromage.com

You use your own WIFI to run a program from the pixelblaze.com.

The control board:

Power supply 5 V, 1 A.

Fancy! Look like a lot of work :-)

Raspberry is fun, what kinda developing environment? Still

C?

Check inside please:

The operating system is Linux.

https://en.wikipedia.org/wiki/Raspberry_Pi_OS

The developing environment is a Unix-like:

 

 

The programing languages could be C, C++, Python etc.

This book is very useful:

The author uses Python:

 

 

 

Check inside please:

For Arduino,

it tookd me around 30-60 minuts to download the Arduino software and add new libraries.

For each program, it  probably took me around 30 minutes.

For Respberry Pi 4,

it took me at least two more days to download the operating system, get used to the new operating system and make it work.

For the hardware of connecting 9 matrix boards, it took me around 3-4 days.

Haha! Good job but I'm done with all that geek work :-)

Linus? Sounds familiar. What does 'uname -a' say?

Fantastic! 圣诞装饰也这么科技范儿。真会玩！

Linus系统，和windows比起来，据说不会那么容易中电脑病毒。

That's what I thought. Linux (created by Linus :-)

Android operating system is based on Linux

https://en.wikipedia.org/wiki/Android_(operating_system)

Android is a mobile operating system (32-bit and 64-bit) based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.

Just like C is created by C.

OK. Didn't know Dennis Ritchie's nickname was C? It might :)

Not terribly hard, in fact, it is very easy.

You could do it (one of Arduino projects) yourself for under $50 in less than 2 hours.

这业余爱好专业。

C is developed from B

It was developed to cover all the inabilities of B language (simplified version of BCPL). So, it was just named C as it is next to B in the English alphabets. C is the only programming language that exists for such a long period and still it is widely used.

Sure.

Arduino could be used for kids at age 6

In wikipedia

https://en.wikipedia.org/wiki/Arduino.

the Arduino was described as designed for "novices" and "beginner hobbyists":

The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea, Italy,[3] aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats, and motion detectors.

Arduino could be used for kids at age 6,

for example, if you type "Arduino for kids" in Amazon, you will get (you will find the following Arduino kits for 6, 8 and 12 years and up on the bottom):

 

 

If you type "Arduino for kids book" in Amazon, you will get
