Example Testing

We have already installed Thonny IDE. Now let's use the simplest approach to do an experiment lighting up the blue LED. Don't worry about understanding the code yet — later chapters will explain it. The main goal here is to familiarize you with how to use the MicroPython programming software Thonny and understand its principles. Here's the procedure:

Connect the development board. In the local file area at the top left of Thonny, locate the main.py file under WalnutPi PicoW (ESP32-S3) Resources Download\02-Example Programs\1.Basic Experiments\1.Light Up the First LED. Double-click to open it and you'll see the relevant code appear in the programming area on the right.
