How to use the camera module on a Raspberry Pi 3 running Fedora 29?

LibreOffice Impress, has a feature useful to switch presentation slides using an Android app. It is a very nice feature, but the last time I used it (on version 5) it was a little unreliable.

So, what about an handmade solution? Just for fun. You need a micro:bit and a Linux (Fedora) workstation (equipped with Bluetooth).

Continuing to explore the GPIO and the devices and sensors we can use with Fedora installed on a Raspberry Pi 3, in this post I will describe how to use a 1wire temperature sensor, in this case a DS18B20.
