What is Raspberry Pi?

A computer that fits in the palm of your hand with a price tag as low as five dollars the idea was born in 2006 and the first commercial unit was launched in 2012 and since then it’s evolved into one of the best selling computers in the world.

Raspberry Pi a Basic IntroductionIt’s named raspberry because computer companies like to name themselves after fruit and pie for the python programming language not only is the computer tiny but it can also be quite powerful with a Quad-Core processor and up to 8GB of RAM. They’re great for building your own IoT prototypes robots security cameras web servers and many other fun projects.

Raspberry Pi moduleWhen you unbox your Raspberry Pi 4 you’ll notice a bunch of little chips and connectors in the center we have our CPU and RAM that is the brain of the operation nearby is the WIFI Bluetooth module that can wirelessly connect to the outside world. At the top, we have a general-purpose input-output connector for connecting other electrical devices. To the right, we have an ethernet connection along with four USB ports on the bottom. We have an audio jack to connect speakers or headphones and a CSI camera connector for building your own custom camera micro.

But most importantly flip the raspberry pi over to find the micro SD slot think of it as a hard drive that contains the operating system required to interface with the hardware you can use the Raspberry Pi like a normal desktop computer by connecting a keyboard mouse and monitor.

Raspberry Pi projects When you power it up the first time you can install any operating system you’d like but most beginners will take advantage of the noobs installer which installs a flavor of Linux called Raspberry Pi OS. Now that you’re in you can program it to take over the world you might connect some leds to the GPIO header then control them with a Python script or you might add a camera then connect to WIFI to build your own home security system from scratch the possibilities are limited only by your imagination.
