Raspberry Pi Bumper Button Holder by techyg

Last crawled date: 3 years, 1 month ago

This thing mounts to the Raspberry Pi B+ Bumper case and allows you to put in a "Big red button". The button can be used for just about anything you can think of. Just write some code and you're off to the races.
Bumper case design is here: https://www.thingiverse.com/thing:629886
I use my Raspberry Pi with my 3d printer. When it is turned on, the webcam and wifi module are running, and I don't want those to be left on constantly. SO when I am done printing, I press the button and make the Pi sleep. When I want to start printing again, I press the button and the Pi wakes up. I prefer using a physical button next to the printer, which is why I do this rather than connecting to the pi using my computer.
The button is wired to pins 5 and 6. I set up a script that shuts down the pi when you press the button, or wakes the pi up (if the pi was shut down previously).
