I'm struggling with a few things and thought i'd ask. i appreciate any advice in advance. Boy is it windy here! Yikes!
i'm building a portable (3.7V 3800 mAh RPi PowerPack V1.2) retropie project that will; hopefully, play a few old arcade style games on a 3.5 LCD touch (i don't need the touch)screen, play audio through a tiny speaker from the audio jack, accept a wii nunchuck 12c input for the joystick and C and Z buttons, and accept 2 5V LED arcade buttons/micro switches.
I plan on installing the on/off button from halt state so that i can power down the pie from the outside of my project rather than opening it all the time. I would like the arcade buttons to light up when the unit is turned on. Is this possible? i think i will only have the one GPIO pin(4) available for power at 5v. if it IS possible, what type of resistors should i use? can i somehow power both LEDS from the one pin? is it not worth it? hahah.
