Raspberry Pi is a credit-card sized computer aimed at providing a computer to everyone on the planet. It is aimed at teaching computer concepts while being low at price. Raspberry Pi is intended to provide a base on which everyone can learn programming while enthusiasts can make various projects. It serves as an efficient base due to its low cost and the number of interfaces available. The Raspberry Pi can be used instead of a personal computer, but with some limitations due to its limited processing power Arduino is an open source platform that offers a clear and simple environment for physical computing. It is now widely used in modern robotics and IoT applications, because its low cost, ease of programming and rapid prototyping capabilities.
