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.
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.
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):

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.

Respbarry Pi 4 project:
Materials:
RGB LED matrix, 64x64 pixels, P3, 9 pieces. the resolution of the display is 192x192 pixels.
The matrix display boards:
Raspberry Pi 4 board:
Power supply, made of a PC AT power supply:
Operating system: Linux
method:

The operating system is Linux.

The developing environment is a Unix-like:
The programing languages could be C, C++, Python etc.
https://en.wikipedia.org/wiki/Raspberry_Pi
This book is very useful:
The author uses Python:
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.

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