When it comes to our hardware projects, we have access to a wide variety of controller board options. Arduino and the Raspberry Pi are two of the most well-known options.  Difference between Arduino and Raspberry Pi are as below:   Arduino  Arduino is a programmable USB microcontroller that is available under an open-source licence.  The central processing unit (CPU), random access memory (RAM), and programmable read-only memory (ROM) are all components of the microcontroller found in Arduino boards. Additional hardware is included on the Arduino Board to facilitate programming, power supply, and IO (Input/Output) communication.  Using Arduino, we can control motors and LEDs in addition to interfacing with sensors.  It features a straightforward structure, both in terms of its hardware and its software.  Utilizing the open-source hardware and software files that are provided by Arduino, it is feasible to construct your very own Arduino board.  It is used to do one activity at a time in its entirety.  Raspberry pi  It is a minicomputer that is based on microprocessors (SBC).  The microcontroller used in Raspberry Pi SBC (single board computer) Arduino boards comprises a central processing unit (CPU), random access memory (RAM), and read-only memory (ROM). Additional hardware is included on the Arduino Board to facilitate programming, power supply, and IO (Input/Output) communication. comes equipped with everything necessary to operate a computer, including a CPU, memory, storage, graphics driver, and ports, among other components.  When it comes to creating Python-based apps, it performs quite well. On the other hand, the Raspberry Pi boards feature a quite intricate architectural design.  Because its source code is not freely available to the public, the Raspberry Pi cannot serve this function.   It can run software, accessing the internet, writing code, and doing a variety of other things all at the same time.
