I have recreated an Arduino circuit I had to make for class, just to see how tinkercad works.
I then copied the code I used for my project (this code works and compiles just fine in Arduino IDE on my PC) and pasted it into the code section.
However when I go to run simulation it pics up an error claiming a statement in my function is undeclared and refuses to run. However this code works just fine in the real world.
Any ideas what is wrong?
It could be that you're using a library that isn't supported in TinkerCAD Circuits. Other than that, it's difficult to determine the problem unless you can post your code.

I have posted the code that compiles on the IDE on my PC.
Hi Sofia,
I've created a circuit based on your code and it worked! Here's a link to the circuit
https://www.tinkercad.com/things/aOhhOtjp8DL-binary-to-decimal-solution
I made one minor change to your code (as it was stopping the compiler). The other thing that may have caused it not to work for you is that you needed to set the 7 Segment Display to Common Cathode - it defaults to being Common Anode.
Hope that helps,
Miles.
I ran it in Tinkercad and at first it said readDIPsw was not visible in this scope so I moved it above the loop function and it ran fine. I don't see why it was not visible before, it should all compile before running but maybe try that.
