I am trying to upload code to my watch that I made from Adafruit's kit. I get the following error:
Arduino: 1.8.5 (Linux), Board: "LilyPad Arduino, ATmega328P"
Sketch uses 24134 bytes (78%) of program storage space. Maximum is 30720 bytes.
Global variables use 1416 bytes (69%) of dynamic memory, leaving 632 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied
An error occurred while uploading the sketch
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Will someone please help me? I am also getting a similiar message when trying to upload code to an Arduino 101.
