Raspberry Pi GPIO programming in C

Steve Chamberlin has written an article about Raspberry Pi GPIO programming in C: The Raspberry Pi’s 40-pin GPIO connector often gets overlooked. Typical Pi projects use the hardware as a very small desktop PC (RetroPie, Pi-hole, media center, print server, etc), and don’t make any use of general-purpose IO pins. That’s too bad, because with a […]

Raspberry Pi web server using flask to control GPIOs

Rui Santos from Random Nerd Tutorials writes: In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a relay or a transistor). In order to create the web server you will be using a Python microframework called Flask. […]

Raspberry Pi level shifters and monitoring

Stuff4Pi posted his ConvertPi, a Raspberry Pi GPIO full level converter & monitoring, in the project log forum: I would like to introduce my first Raspberry board: a GPIO bi-directional level translator (3.3V <-> 5V): – This is an in-between expansion board that you plug in the RPi P1 connector which gives a bi-directional level […]
