"The Raspberry Pi has sold millions of units worldwide since its first release in early 2012 and is still extremely popular.
Many Raspberry Pi users not only have one single-board computer at home, but sometimes 4-5 of them.
One functions as an HD media player with external hard disk for the home cinema or as an Internet radio with display, the next as a webcam server for camera surveillance with live streaming to the cell phone, then another for home automation such as heating or lighting control and yet another as a simple WLAN printer server or as a mini-computer for general Internet surfing, to name just a few application scenarios.
As you can see, the little ""jack-of-all-trades"" can not only do a lot, but is also extremely inexpensive and that's what makes it so attractive.
All you need to bring along is a penchant for programming and not even that, because you can also simply program it according to instructions from forums or books, or simply install a ready-made image on the Raspberry Pi - go for it!What are the differences between a Raspberry Pi 4 B and a Raspberry Pi 5 B?Old Raspberry Pi 4 B1.
