Displays are a handy addition to many Maker projects communicating with us and giving us feedback. As a human-machine interface, they display the status of a device or various sensors, for example, and thanks to their ability to display graphics, even complex information such as symbols, diagrams or animations can be displayed.

What a few simple LEDs sometimes can’t do, a display can easily do thanks to graphic libraries. What tools the Adafruit GFX Library I will show you in this workshop how you can create controllable loading bars from triangles and squares even as a display novice – we will only devote ourselves to bitmaps next time.

From the countless screens that Adafruit supported, I have selected two that will give you a direct start: a monochrome OLED display (SSD1306) and a TFT touch color display (ILI9341).
