Details on wiring a Pi power switch #
Wiring up a Pi power switch seems like it should be the simplest thing imaginable. It is not. There's a surprising large number of things you'll need to work through. That said, it's not that hard once you sort through a gazillion how-to guides to find the one that makes sense.
The key is to use a momentary switch with a resistor built in, so you're protecting the Pi. I used this power button with LED and have been happy with the results.
Note when you're following the instructions, the files don't have to be written -- they're in the repo. Just use
cp to move them where you need them and be sure to
chmod them to set the permissions.
A simple tutorial
took care of the LED portion of the switch.
One catch: because there's a power switch and an LED, you have to think through the GPIO pins a little more. I used 5 and 6 for the Power button, as outlined in the instructions, then used 8 and 14 for the LED.
