D1 mini arcade button enclosure

This is an enclosure that houses a D1 Mini style microcontroller and a 30mm Sanwa-style arcade button.

You can then use ESPHome to create and flash the firmware for the microcontroller. I've included a sample YAML configuration file below. Make sure to add your MQTT broker and WiFi information.

esphome:
  name: arcadebutton

esp8266:
  board: d1_mini

  # Enable fallback hotspot (captive portal) in case wifi connection fails

binary_sensor:
  - platform: gpio
    pin:
      number: D4
      inverted: true
      mode:
        input: true
        pullup: true
    name: "button"

Simply solder a pin header between D4 and GND to connect your button inbetween. I used these cheap little wire harnesses that come with plugs that i got with an arcade controller kit.I used cheap little wire harnesses that come with plugs.

The mounting bracket is a bit loose. Add some spongey stuff to the flat side and it'll be good. I may try to design a better version later, but it works for now.
