TUTORIALS
TROUBLESHOOTING
When you upload your sketch, you may see an error like:
avrdude: ser_open(): can't open device "\\.\COM6": Access is denied.
Failed uploading: uploading error: exit status 1
This means another program is already using that COM port. Most often, it’s because the Arduino IDE’s Serial Monitor is open. To fix this:
- Close the Serial Monitor.
- Disconnect USB cable from PC, then reconnect again.
- Upload your code again.
- Once the upload succeeds, reopen the Serial Monitor if you need it.
