Difference between Arduino and Raspberry Pi

There are a wide variety of controller boards that we can use for our hardware projects. The two most popular among them are: Arduino and Raspberry Pi. Arduino is based on the ATmega family and has a relatively simple design and software structure. Raspberry Pi, basically is a single-board computer. Both of them have a CPU which executes the instructions, timers, memory and I/O pins. The key distinction between the two is that Arduino tends to have a strong I/O capability which drives external hardware directly. Whereas Raspberry Pi has a weak I/O which requires transistors to drive the hardware. 

Let’s see the difference between Arduino and Raspberry Pi :-

S No.	Arduino	Raspberry Pi
1.	In the year 2005, the classrooms of the Interactive Design Institute in Ivrea, Italy, first introduced the Arduino board.	In the year 2012, Eben Upton first introduced the Raspberry Pi device in February.
2.	Control unit of the Arduino is from the Atmega family.	The control unit of Raspberry Pi is from the ARM family.
3.	Arduino is based on a microcontroller.	While Raspberry Pi is based on a microprocessor.
4.	It is designed to control the electrical components connected to the circuit board in a system.	While Raspberry Pi computes data and produces valuable outputs, and controls components in a system based on the outcome of its computation.
5.	Arduino boards have a simple hardware and software structure.	While Raspberry Pi boards have a complex architecture of hardware and software.
