Hello,
Please help.
I have a problem in uploading my program into the arduino board.
It was working properly for the past few month. Suddenly this error has come up.
Please help.
The error message
Arduino: 1.6.13 (Windows 10), Board: "Arduino/Genuino Uno"
Sketch uses 928 bytes (2%) of program storage space. Maximum is 32,256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "\.\COM5": The semaphore timeout period has expired.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
