First time poster.
Not long ago I purchased my first Pi, a Zero W. Loaded Retropie and am enjoying so good old gaming.
I have now started constructing a barrio arcade to house this.
In doing so I will be using LED arcade buttons, approx 20. The button kit I was looking at had 3 pin encoders for the LEDs which are powered from the Pi and not a seperate power supply.
My question is, is this do-able with a Pi Zero W or will the power consumption be too great and case issues?
Would I be better to use 2 pin encoders and then powering the LEDs direct from a 12v power supply?
Sorry if the above is a stupid question as I am still learning here.
