Remove any unneeded USB devices that may be using the ports. Try connecting your board with a different cable, or testing your cable with a different device. Make sure you are using a data transfer USB cable (charge-only cables will not work). Avoid using a USB hub if possible, or try a different hub. If possible, connect the board directly to a USB port. Try disconnecting and reconnecting the board to the computer, and confirm that the power LED (often labeled “ON”) is lit. Reset your board by pressing the RESET button (a white or blue push button). If this doesn’t work, try restarting your computer. If your board is missing, see If your board does not appear in the port menuĬlose other instances of Arduino IDE, serial monitors, and other software that may be blocking the port. Make sure you have selected the right board and port correct board under Tools > Board and Tools > Port.įor instructions, see Select board and port in Arduino IDE After each step, try uploading your sketch again. Most errors can be solved by following these steps. Note: The error text may be different depending on your system language.
