Visualize data with Kivy
Many applications for the Raspberry Pi include the measurement and visualization of data. This series of articles shows you how to realize that.
We will start with creating some hardware. A desktop stand for the pi with touch display as well as a sensor HAT to measure temperature and humidity.
After we took care of the hardware ist it goint into coding. You will learn how to install Kivy, create a framework for the visualization and finally we are going to write a couple of apps. They will be using the data from our sensor HAT to display temperature and humidity in a romm as well as we are going to write a weathe app using the API from OpenWeatherMap. An App showing the Pollen load in your area as well as a simple app to inform you about the state of the Covid pandemic.
