I'm here and I'm starting using MicroPython and really want to enter in this community. Now I'm testing some code in the simulator called Unicorn at the official site and is answer me a very strange error, here is the error message
Traceback (most recent call last):
File "<stdin>", line 96, in <module>
AttributeError: 'Switch' object has no attribute 'callback'
I don't know which version is using but it seems to me really strange. Here is the code if some one can say me if it's wrong.
