Topic: COM Port 3 Not Found? (Read 1 time) previous topic - next topic


I've been struggling to find an answer to this seemingly simple problem: My computer won't recognize COM Port 3. It recognizes my Uno as a device on COM3, but the IDE seems to not recognize it. I noticed the TX/RX lights aren't lightning, but this may just be because it's not receiving a signal... The board was working perfectly fine earlier today, but this problem began an hour ago. I've tried rebooting my computer, unplugging and replugging the cable, resetting the board, and updating the drivers; nothing works! If anyone can offer possibilities for why I'm getting this error, I'd be very thankful!!
Is it a 270 or a 330 resistor for LEDs? Aw hell, I just blew another one.
