Notes
- Select LED color. I used orange clear LEDS but orange diffused body LEDs might be better since clear LEDs reflect background light.
- LED ballast resistor. 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.
- 0.1" pins. Select either SS12D00G3 3 pin slide switch or 3 pin headers.
