Voltage Interfaces

In my experiences with the Propeller Microcontroller (a 3.3v device), I have had to interface numerous 5v devices to it. At first, I thought it would be alright just to hook 5v right to the I/O pin. However, after I started loosing I/O pins, I learned that it isn't a 5v tolerant chip. After that, I started using proper interfaces (resistors, FETs, etc). Anyway, Spark Fun Electronics posted a tutorial on voltage interfaces this morning. Thought everyone might like to read it. Link
