Hi Christian,
Do you see the footer of that window where it says “9600 Baud”?
You need to select the option “115200 Baud”, so the serial monitor can receive the messages from the ESP32 and display them correctly. After changing the baud rate to 115200, restart your board.
Does it work now?
Thanks!

You’re welcom! If that happens again later in the course, double-check in the setup() function when I do:

Serial.begin(115200);

The value inside those brackets is the baud rate that your Arduino IDE serial monitor should be set to. Thanks!
