Skip to main content Troubleshooting Steps for ItsyBitsy
- Is the ItsyBitsy powered/is the USB plugged in?
- Are you using a micro USB data cable? some cables only supply power, not data.
- Are you working in Mu editor?
- Are the sensors and actuators plugged into the correct ports?
- If you’re using Chainable LEDs, are they connected to the IN side? (See the white arrow)
- Chainable LEDs don’t need to return to the board.
- Is the correct code saved on the ItsyBitsy? (Not locally on your laptop)
- Does the file have the name “code.py”?
- Mu indicates where it saves it when you click save, at the very bottom left.
- Have you clicked the reset button once? (button with “rst”)
- If you open the Serial monitor and save again, is there an error in the console?
- If the error contains “Module”, check if all libraries are on the board.
- You can find the libraries by googling “CircuitPython libraries” or download them from https://circuitpython.org/libraries.
- We’re using version 9.X
- If the error contains “INDENT”, then there’s too much or too little TAB/(SPACE) somewhere. Usually at the beginning of a code line.
- If the error contains “SYNTAX”, there’s likely a missing “:” or a keyword (such as IF or Print) is mistyped/used incorrectly.
- Are you in REPL mode (Do you see “»>” in your console)? You can exit by typing “ctrl + d”, or a few times “ctrl + c” and then “ctrl + d”.
- Make sure you read what the code does and follow all steps.
