Arduino vs. Raspberry Pi: When it comes to IoT-based projects, a micro-controller considers as the backbone of the project. Microcontroller is a electronic hardware component. For that, we need to choose a suitable performer micro-controller that meets the project’s requirements at low cost or flexibly. To choose suitable one we will see Arduino vs Raspberry Pi difference in this tutorial. A micro-controller is a compact integrated system circuit that we can use to perform particular operations in embedded systems. Micro-controllers play a significant role in today’s digitally growing or technological world. It is a small and low-cost micro-computer and performs specific tasks like receiving the remote signal, displaying microwaves, etc. Micro-controllers include processors, memory types (ROM, RAM, EPROM), serial ports, peripherals (timers, counters), etc.

The architecture of a Micro-Controller
Many types of microcontrollers are there available in the market. For our project, we must choose the micro-controller considering some factors in our mind. Factors like scalability, functionality, flexibility, cost, power requirements, processor, etc. To select a suitable micro-controller for our project, we will see the differences between two well-known micro-controllers: Arduino and Raspberry Pi.
Arduino is a microcontroller board and an easy-to-use open-source electronic hardware component to use in your IoT projects. Beginners can use it who have insufficient knowledge of electricity, programming, and electronics. It is a development board loaded with a micro-controller chip. IoT-based projects are a combination of hardware and software. Arduino is a hardware component, and it has its IDE to write program code to function Arduino board. Below are given both Arduino board and Arduino IDE:
Raspberry Pi is neither a microprocessor nor a microcontroller. It is a single-board computer that contains a SOC (System On Chip – Has multicore processor, GPU, ROM, I/O Peripherals inside it.), DDR RAM, Ethernet port, USB host, micro HDMI on it. Raspberry Pi is a cheap or low-cost computer that runs Linux OS. Still, it also provides a set of GPIO (general purpose input/output) pins, allowing you to control electronic components for physical computing and explore the Internet of Things (IoT). Raspberry Pi does not have a particular IDE. It can run with multiple languages like Python, R, etc.
Arduino vs. Raspberry Pi
Arduino has a relatively simple design and software structure, and it is ATmega family based. Raspberry Pi is a single-board computer. Both of them have a CPU that executes the instructions, timers, memory, and I/O pins. The main difference between these two is that Arduino tends to have a solid I/O capability which drives external hardware directly. In comparison, Raspberry Pi has a weak I/O, which requires transistors to operate the hardware.

A Linux-based operating system is required to run it.
In conclusion, we have discussed microcontrollers. Arduino is microcontroller-based, and raspberry pi is microprocessor-based. They both are electronic hardware components that are used for IoT-based projects. For every different project, it requires a various microcontroller according to the project needs. We had some discussion between two microcontrollers, Arduino vs Raspberry Pi, to choose what is needed.
