Important

The Arduino Playground offers test code, templates, and experiments with well-known Arduino sensors, peripherals, and displays (like OLED, TFT, LCD, and Dot Matrix).

While most installations and uses are straightforward, some require additional libraries and special wiring connections. I became confused while following numerous tutorials from blog posts, forums, and YouTube videos to set up these peripherals.

So, I decided to document my process, including the challenges I faced and the discoveries I made. I also wrote some utility functions to solve common problems.
