Why isn’t my Arduino connecting to my computer?
First make sure your board is on (the green LED is on) and connected to the computer. The Arduino Uno and Mega 2560 may have trouble connecting to a Mac through a USB hub. If nothing appears in your “Tools > Serial Port” menu, try plugging the board directly to your computer and restarting the Arduino IDE.
How do I know if Arduino is detected?
In order to check if your board is connected to the Arduino IDE, you can go to Tools -> Port. It should show all the available COM ports. Now, you can disconnect your board. If one COM port disappears, then you can be sure that your board was connected and detected by the Arduino IDE.
How do I reset my Arduino serial port?
The Arduino is reset by opening the serial port (auto reset) and/or on power up. You can prevent the auto reset from the serial port, temporarily, by connecting a 10uf cap between the reset pin and ground. If using an electrolytic cap, make sure to observe polarity.
Why is my Arduino not connect to my computer?
If your Arduino is not recognized. then uninstall the driver, remove the Arduino, reinsert the Arduino, find the unrecognized device, right click “Update driver”, and then click “Search automatically”. This should fix 99 out of 100 problems. If the Arduino is not recognized, update the driver.
How do I open port COM1?
Right-click on Communications Port (COM1) and select Properties. In the Properties window, click on the Port Configuration tab and then click on Port Setting.

When you connected Arduino device make ensure the following 1) check in device manager-> port section-> Arduino board has detected or not. If detected port but highlight with yellow color , That means you not installed driver properly
Is it possible to connect to Arduino Uno with Linux?
The serial port was available, and I was also able to successfully upload to the Arduino Uno. As a Linux user you’ll need to be a member of the group dialout to be able to read and write to any /dev/tty* connections. Thus, making the connection world-writable or running the Arduino IDE as root is both not the way to go.
How to find the port to which Arduino IDE is connected?
Go to “Port”. Select the port to which Arduino is connected. (If no other external drive is connected except Arduino,there will be only one port) This will tell Arduino IDE the port to which your hardware is connected.
Why won’t my Arduino board upload to the Arduino IDE?
@abdullahmc Try double tapping the reset button (two times in quick succession) this puts the board into bootloader mode, (the PC should change COM port). If available select the new COM port in the Arduino IDE and try uploading oncemore. Failing that, try wiggling USB connector in the PC and MKR board sockets.
