TROUBLESHOOTING
I still get an error when
uploading my code
If you’re sure you have the correct Board selected but you still can’t
upload, check that you have selected the correct serial port. You can
change this in Tools > Serial Port > your_serial_port.
Which serial port is
the right one?
Depending on how many devices you have plugged into your computer,
you may have several active serial ports. Make sure you are selecting the
correct one. A simple way to determine this is to look at your list of serial
ports. Unplug your RedBoard from your computer. Look at the list again.
Whichever serial port has disappeared from the list is the one you want
to select once you plug your board back into your computer.
My code uploads, but my
LED won’t turn on
LEDs will only work in one direction. Try taking it out of your
breadboard, turning it 180 degrees and reinserting it.
Still not working?
Jumper wires unfortunately can go “bad” from getting bent too much.
e copper wire inside can break, leaving an open connection in your
circuit. If you are certain that your circuit is wired correctly and that
your code is error-free and uploaded, but you are still encountering
issues, try replacing one or more of the jumper wires for the component
that is not working.
