When it comes to performance, Raspberry Pi has the edge over Arduino due to its full computing power. Raspberry Pi boards pack a punch with their multicore processors, RAM, and ample storage options. This makes them capable of running complex applications and handling multiple tasks simultaneously.

Arduino, on the other hand, is a microcontroller-based board optimized for low-level tasks, such as reading sensors, controlling motors, and interfacing with other hardware components. Its limited computing power and memory make it suitable for lightweight projects where simplicity and real-time control are key.

Key takeaway: For projects that require heavy computation and multitasking capability, Raspberry Pi is the superior choice. However, if you need precise timing, low power consumption, and direct hardware control, Arduino is the way to go.

Power Requirements: Arduino vs Raspberry Pi

When it comes to power requirements, Arduino and Raspberry Pi have slight differences. Let's explore them in more detail.

Arduino

Arduino boards are designed to be power-efficient and can run on low power sources, such as batteries or small power supplies. This is because Arduino boards are optimized for microcontroller-based tasks and are designed to consume less power.

Raspberry Pi

Raspberry Pi boards, on the other hand, are more power-hungry due to their computing capabilities. They require a stable power supply, typically 5V with a recommended current rating. Although they are still relatively power-efficient compared to traditional computers, Raspberry Pi boards consume more power than Arduino.

Key takeaway: If power efficiency is a crucial factor for your project, Arduino's low power consumption makes it a better choice. However, if power consumption is not a major concern, Raspberry Pi's processing power outweighs its higher power requirements.

GPIO Comparison: Arduino vs Raspberry Pi

One of the key features of both Arduino and Raspberry Pi boards is their ability to interface with external devices through their GPIO (General Purpose Input/Output) pins. Let's compare the GPIO capabilities of Arduino and Raspberry Pi.

Arduino

Arduino boards are equipped with digital and analog I/O pins, allowing you to read sensor values and control actuators directly. They offer a wide range of GPIO pins, making it easy to connect various sensors, motors, and other components. Arduino's GPIO pins are known for their simplicity and ease of use.

Raspberry Pi

Raspberry Pi boards also have GPIO pins that allow for interfacing with external devices. However, compared to Arduino, Raspberry Pi's GPIO pins have additional functionalities, such as support for I2C, SPI, and UART protocols. This makes Raspberry Pi more versatile when it comes to communication with other devices.

Key takeaway: If your project mainly involves reading sensor data and controlling actuators, Arduino's GPIO pins provide a simple and straightforward solution. If, however, you require additional communication protocols or need more advanced interactions with external devices, Raspberry Pi's GPIO capabilities offer greater flexibility.

Add-ons: Arduino vs Raspberry Pi

Both Arduino and Raspberry Pi support various add-ons and extension boards to enhance their functionality. Let's take a closer look at what each platform has to offer.
