Before we begin, let me give you a brief introduction on Raspberry Pi. Well, a Raspberry Pi is a low budget, small credit-card sized ARM board, that acts as a computer. This board is developed by Raspberry Pi Foundation , UK with the intention of promoting the teaching of basic computer science in schools. The processor at the heart of the Raspberry Pi system is a Broadcom BCM2835 system-on-chip (SoC) multimedia processor. This means that the vast majority of the system’s components, including its central and graphics processing units along with the audio and communications hardware, are built onto that single component hidden beneath the 256 MB memory chip at the centre of the board. It’s not just this SoC design that makes the BCM2835 different to the processor found in your desktop or laptop, however. It also uses a different instruction set architecture (ISA), known as ARM. The ARM-based BCM2835 is the secret of how the Raspberry Pi is able to operate on just the 5V 1A power su
