Hi. I have just got the arduino nano esp32 for a school project. When i try to upload smth, it says "Arduino: 1.8.19 (Linux), Board: "Arduino Nano ESP32, With FAT partition (default), By Arduino pin (default), Normal mode (TinyUSB)" Sketch uses 285869 bytes (9%) of program storage space. Maximum is 3145728 bytes. Global variables use 30732 bytes (9%) of dynamic memory, leaving 296948 bytes for local variables.

" I am using Linux/raspbian. my arduino nano esp32 is in regular mode/ running the preloaded sketch. and can someone pls tell me what all these rgb light sequences are and help me upload? Thanks. I gotta finish this in 24hrs, so pls help. :smiley:

Your user is not in the correct group. Most likely you need to add it to "dialout" and "plugdev".

OK but how? Is there some special sudo command or smth? And pls explain all these light sequences to me. Thx

I tried adding myself with "sudo usermod -a -G dialout minecraft", but got{Arduino: 1.8.19 (Linux), Board: "Arduino Nano ESP32, With FAT partition (default), By Arduino pin (default), Normal mode (TinyUSB)" Sketch uses 285869 bytes (9%) of program storage space.
