Quick question - 0.1"f capacitor?

Other Hardware General Electronics
1

I was reading the ShiftOut tutorial, http://www.arduino.cc/en/Tutorial/ShiftOut, and for step two it says the following:

"From now on those will be refered to as the dataPin, the clockPin and the latchPin respectively. Notice the 0.1"f capacitor on the latchPin, if you have some flicker when the latch pin pulses you can use a capacitor to even it out."

How am I supposed to pronounce 0.1"f? Is it micro, nano, or what?

Any info would be great. Thanks!

It is 100nF and not needed at all. I'm speaking from personal experience.

If it should be required to run the circuit nevertheless, something else is wrong.

Thanks a lot - that's all I needed to know! :slight_smile:

Not only is it not needed, its potentially burning out the output pin. Someone needs to fix the tutorial.

Thanks everyone - much appreciated. :slight_smile:
