We’re going to use Python to learn to code. These are then interpreted into machine language, which the computer understands.

This is written using easy-to-understand functions like print(). Instead, we use a coding language to program. It’s possible to use machine language and send binary instructions directly to a computer, but this isn’t where any sane person starts (or ends if they want to remain sane). Obviously, it’s not that easy for humans to talk directly to computers. Everything you see on the screen, hear from the speakers, and type on the keyboard is billions of switches being turned on and off. There are 8,589,934,592 of them in its 1GB of RAM, to be exact.Īll these switches can be set to high or low, which is typically represented as 0 (for low or off) and 1 (for high or on). Program a Raspberry Pi: Inside your computerĪt the heart of your Raspberry Pi are billions of voltage switches known as binary digits (or ‘bits’ for short). With just a few variables, a smattering of flow, and some functions, you can get a computer doing all the hard work for you. One thing that may surprise you when you begin programming is just how little you need to know to get started. Your recipe could make a scrummy chocolate cake or a delightful batch of doughnuts, depending on the variables (the ingredients) it has. Programs also make decisions, and different paths through a program can be taken. A program may contain loops that make it do the same thing over and over again. So you can get a machine to bake a thousand cakes without ever getting tired. The real miracle of computers is that they can do the same thing repeatedly.

You follow the instructions from the recipe one line at a time and end up with a tasty cake - and that’s no lie. It has a list of ingredients, called ‘variables’, and a list of instructions, known as ‘statements’ or ‘functions’. The dictionary definition is a “set of instructions that makes a computer do a particular thing.”Ī computer program is a lot like a recipe. Program with Python in the Raspberry Pi terminalīefore you learn programming with a Raspberry Pi and Python, let’s look at what a program actually is.What's going on inside a Raspberry Pi when you run a program.In this article we're going to look at how you create a program on a Raspberry Pi.
