More people who use DACs...

....but don't understand them as well as Edwin:

"When the fan is on, a 4-bit binary value is specified by the MCU with 4
port pins. This value is then converted to a 0-12V voltage by the DAC,
with 16 discrete voltages in between."

But, what would *they* know? It's just Cornell University...
