These are some frequently asked questions from people in my class and myself. These include problems with coding, physically building and things in general, along with a possible solution too.
Make sure to check each line of code, because you have probably missed a semi-colon ; or a bracket. If that is all good, check in tools at the top of your screen that your Arduino nano board is linked properly. It should be connected to the nano board and serial port.
Read what the error is and try to understand what is wrong. Also read what the error is and try to understand what is wrong.
Double check that the wires are connected to the right pin on the nano board according to your code. And remember that the brown wire goes to the GND pin. (Look back to step 4 for further explanation).
Just take off the top part and rotate it so the finger is in its normal position.
Maybe compare your code to someone else’s code that does work and see what you have missed.
Make sure that the batteries are the right way round, the plus and minus. If it's on the nano board should light up.
Just let the glue heat up longer before using it, or you can heat the set glue and pick it off with something like a metal wire and start again.
