voltage protection - Best way to protect a digital output ...
One of the suggestions there for output pins was: Put a 30mA resettable fuse (PTC) in series with every I/O pin. Not only is the current safely limited to 30mA under all conditions (more on this below), but the built-in 220 ohm resistance of the fuse naturally limits the current to 5V/220 = 23mA right off the bat.

Microcontroller Input Protection Techniques - Kevin's Projects
 A recent project I have been working on required a single input from a pushbutton. Simple enough I thought, as this is a very common thing in most electronic projects. Especially those with microcontrollers. My initial thought was to carelessly place one leg of the pushbutton to ground and the other to the ...

Help with PTC Overload Indicating Circuit - Forum - All About Circuits
 I think the 100 ohm resistors will have 30mA/.09W flowing through them when PTC's are in the low resistance state. When in the high resistance state since there is only .6A available, so it won't "make it through" the resistor allowing the base to be pulled low (and allowing the opening of the motor switch to ...
