It is a microcomputer motherboard based on arm, with SD / microSD card as memory and hard disk. Around the card motherboard, there are 1 / 2 / 4 USB interfaces and a 10 / 100 Ethernet interface (type A has no network interface), which can connect keyboard, mouse and network cable. At the same time, it has TV output interface for video analog signal and HDMI HD video output interface, All the above components are integrated on a motherboard that is only slightly larger than the credit card. It has the basic functions of all PCs. just connect the TV and keyboard to perform many functions, such as spreadsheet, word processing, playing games, playing high-definition video and so on. Electronic Component Assorted Kit only provides computer board, without memory, power supply, keyboard, chassis or connection.

Raspberry Pi Pico Microcontroller Board is produced through three companies with production licenses, element 14 / Premier Farnell, RS components and egoman. All three companies sell DIY electronics and kits online. You can buy the raspberry pie you want on the fbelec website.

The raspberry pie Foundation provides arm based Debian and arch Linux distributions for public download. It is also planned to support Python as the main programming language, Java, BBC basic (through RISC OS image or "brand basic" clone of Linux), C and Perl,Complete Component Kit for Raspberry Pi

What is Arduino
Arduino is an open-source electronics platform that combines a programmable circuit board (hardware) with a development environment (software) for writing and uploading code to the board to perform specific functions. It is known for its user-friendly nature, affordability, and extensive community support, which makes it widely accessible, particularly for beginners.

The platform's software, known as the Integrated Development Environment (IDE), supports programming in C and C++ languages and is compatible with Windows, Macintosh OSX, and Linux. Arduino boards can be connected to a variety of components, such as sensors, motors, and OLEDs, to perform specific tasks.

What is Raspberry Pi

Raspberry Pi boards are essentially complete computers on a printed circuit board the size of a credit card. These devices contain a central processing unit (CPU), random access memory (RAM), WiFi and Bluetooth connectivity, input/output connectors, Ethernet and USB ports, an audio jack for headphones, HDMI ports to connect monitors, and a micro SD slot. These boards have no internal storage, so an SD or microSD card is necessary for these boards to function.

Raspberry Pi boards can connect to peripherals such as keyboards, mice, and monitors, turning them into fully functional desktops. With built-in Ethernet ports, they can connect to the Internet for browsing, file transfers, and networked tasks. Equipped with powerful CPUs, Raspberry Pi boards are capable of running full operating systems and handling multiple complex computing tasks, making them versatile tools for a wide range of applications.

Difference Between Arduino and Raspberry Pi
Arduino is a microcontroller board designed for simpler, real-time control tasks, such as controlling sensors or automating simple devices, while Raspberry Pi operates as a mini-computer, capable of running full operating systems and managing more advanced computations, like hosting a web server or processing video.

Processing Power
Arduino is primarily designed for microcontroller-based projects. Arduino offers limited processing power. It's ideal for simple tasks, sensor readings, and controlling actuators.
Raspberry Pi functions as a mini-computer, providing significantly more processing power than Arduino. It can handle complex tasks like image processing, video playback, and running operating systems.

Operating System
Arduino operates without an operating system, making it simpler for beginners. Its code runs directly on the microcontroller.
Raspberry Pi runs various operating systems, such as Raspberry Pi OS, Ubuntu, and Debian, offering flexibility and advanced capabilities.

Cost
Arduino is generally more affordable due to its simpler hardware and focus on specific tasks.
Raspberry Pi tends to be pricier due to its increased processing power, memory, and ability to run full-fledged operating systems.

Applications
Arduino excels in robotics and IoT projects where real-time control is crucial, such as controlling sensors or actuators.
Popular applications include weather stations, home automation systems, and wearable tech.
Raspberry Pi is ideal for more complex tasks, like running a home media center, building a web server, or even creating AI-driven applications like facial recognition systems.

Development Environment
Arduino uses a simplified IDE (Integrated Development Environment) that is beginner-friendly.
Raspberry Pi can be programmed using various languages like Python, C++, and Java, offering more flexibility but requiring a steeper learning curve.

Raspberry Pi Applications
Raspberry Pi is a powerful mini-computer that can perform complex and several different operations simultaneously. Its capacity to run full operating systems, along with its GPIO pins for interacting with the physical world, makes it the preferred choice for projects requiring a robust computing environment, such as managing web servers, media centers, games, home security, and automation.
