Shaaban 614 To be able to help you it would really help to know your development environment (what OS are you working on, how are you connecting to the serial port, etc.). The message suggests that another process using the serial port, it could be

as simple as need to close and reopen your terminal emulator. –dlu Nov 26 '15 at 20:01 Im using windows 8.1, and im connecting to the serial port via usb. –M. Shaaban Nov 26 '15 at 20:04 How are you connecting to the serial port (what software are you using to received the serial data)? I don't do much with Windows, but I think the problem that you're having is that your terminal emulator is expecting to see the data on your COM1 port but you're actually transmitting the data over USB and a virtual serial port. The serial monitor in the Arduino IDE picks up the serial port from the setting in the menu Tools > Port (which is also used for your upload), but other programs will need it to be explicitly set. –dlu Nov 26 '15 at 20:09 the software is built in the arduino IDE. I edited the post the code is not uploading, only compiling. –M. Shaaban Nov 26 '15 at 20:18 COM1 is usually reserved for the built in serial port in the computer. Your USB serial port is more likely going to be COM3 or COM11, or even COM23 rather than COM1. Make absolutely sure you have the right COM port selected, and that you have installed the right serial drivers for your board. –Majenko Nov 26 '15 at 20:19 | show 3 more comments 3 Answers 3 active oldest votes up vote 3 down vote I've got an idea.

I'm using the Arduino IDE 1.0.1 and the 64bit version of Ubuntu 12.04. This has been a reoccurring problem since 10.04 and happens to a few other programs that use a serial connection too. I have no problem getting serial data from the Arduino using Python or Screen. The Arduino IDE seems to work just fine otherwise. processing.app.SerialException: Error opening serial port '/dev/ttyACM0'. at processing.app.Serial.

(Port not found) error the serial monitor won't open any port until the IDE is restarted. This happens with any com port number. I don't have this problem under 1.6.4. It is a bit difficult to get the error message. I can get it sometimes by: Plug in the board to USB error opening serial Select a different port from the one the board is on Select the port the board is on Unplug the board from USB Try to open the serial monitor. Console shows Error opening serial port 'COM12'. (Port not found). If that error doesn't show then restart the IDE and repeat the process. Plug the board back in to USB Verify the port shows in the ports menu Open serial monitor. Nothing happens. The same will happen for boards on a different port. It may take a few tries to get the error message. I do not have this problem after the more common Board at COM12 is not available error. ffissore commented Jun 1, 2015 Related to #3255.
