I’m working through the ESP32 starter kit and it TUTs this is only the 2nd TUT 2.2 fading LED and i can not get past this. I’ve followed all the steps repeatedly and this keeps happening.

Please provide a screenshot of your Arduino IDE. And confirm that if you have selected ESP32 as the board? ---

The issue is being fixed by us and it will take some time to complete. The current solution is: Follow our screenshots and install ESP32, choosing version 2.0.14. ![image (23)](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/1X/7fe435a80fed70012e5bc69b5c4ae059716026fd.png) ![image (27)](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/1X/9ff28dc1fa3f0a32310bc5b294f646b83a83cc61.png) The installation will take a long time, so please be patient. After successful installation, you can upload the code again and see if the error message still appears. ---
