Arduino and Raspberry Pi are two of the most popular and widely used single-board computers. They are both open-source platforms and have their own unique advantages and disadvantages.
The main difference between the two is that Arduino is a microcontroller, while Raspberry Pi is a single-board computer.
Arduino is a microcontroller, meaning it can only function as a controller for basic tasks. It is essentially a single-chip computer that is programmed to perform specific tasks. It is ideal for controlling simple electronics such as LEDs, motors, and sensors. For example, it can be used to control a robot or a 3D printer.
Raspberry Pi, on the other hand, is a single-board computer. It is a full-fledged computer with a processor, memory, and input/output ports. It can be used for a variety of tasks, such as running a web server, playing media, or even running a full-fledged operating system. For example, it can be used to create a home theater system or a home automation system.
