Hi, I'm a newbie to physical projects such as teensy, but a long time programmer (iOS)
I have just received my first teensy, a 3.6
It says "Teensy 3.6 pins are not 5 volt tolerant. Do not apply more than 3.3 volts"
Yet when I do the "tutorial 4" project,on this site, I install a button, and that button feeds 5 volts to a pin. The same goes for the next tutorial with a potentiometer. This is because the power coming from the Teensy itself (actually the USB connected to it) is 5 volts.

So this leaves me a bit confused as to the instruction not to apply more than 3.3 volts to a pin.
Sm I not meant to be doing these tutorials? Or am I missing something obvious?
Can someone explain this to me?
Thanks
