Notes
- I used 1K because modern LEDs are really efficient and can get uncomfortably bright with higher current. Vcc is 3.3V, Orange LED drops ~1.8V. Leaves 1.4V across resistor. Equals 1.4 mA with 1K resistor.
- Pick whatever height button you like. I used 9mm tall which is pretty tall but it's what I had sitting around.
