Power management of RPI3 running Moode 4.1
#1
Hi all,
I'm working on my project (build a network streamer with a RPI3 + HifiBerry DAC PRO+, an OLED 16x2 display and a button to wake-up/shutdown the system).
I bought a small card from Mauseberry Circuits that seemed very promising. I bought also a momentary button having a 3V blue LED that I connect to the Mauseberry board (this is the board https://mausberry-circuits.myshopify.com...own-switch )

I try but maybe something goes wrong. When I push the button, the RPI wakes up and the LED light up (very nice !!!), but when I press the button to shutdown the RPI nothing happens...

Maybe I made some errors, and try to understand why.
In anycase, I red that it could be possibile to have the same behavior without the need to use such board. I red that is possible to force the shutdown of the wake-up of the RPI closing the circuit between pins 5 and 6 of the RPI (obviously using by button). 
For example, as described here : https://howchoo.com/g/mwnlytk3zmm/how-to...spberry-pi

My question is about the led. How can I connect the two + and - wires soldered on the button to the GPIO of the RPi? Is it possible? Having a 3V LED, do I still need a resistor between the led and the GND pin ?

thanks!
Andrea
