Got myself a Raspberry Pi Zero W to tinker with. A small one-board computer that is easy to develop software for. I like that. Here are my projects.
This project measures the temperature using a Maxim DS18B20 1-wire sensor, stores the temperature in a Maria DB and displays temperatures on an Apache web page.
I used the project "Raspberry Pi Temperature Sensor: Build a DS18B20 Circuit" and added a database and a web server.
See Temperature/README.md.
