<p>This is an enclosure that houses a <a href="https://amzn.to/3QRIex3">D1 Mini style microcontroller</a> and a <a href="https://amzn.to/3dZKQu9">30mm Sanwa-style arcade button.</a></p><p>You can then use <a href="https://esphome.io/">ESPHome</a> 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.</p><pre><code class="language-plaintext">esphome: name: arcadebutton esp8266: board: d1_mini # Enable logging logger: ota: password: "" wifi: ssid: "YOUR SSID" password: "YOUR PASSWORD" # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "arcadebuttonfallback" password: "asdf1234" captive_portal: mqtt: broker: "YOUR MQTT BROKER" binary_sensor: - platform: gpio pin: number: D4 inverted: true mode: input: true pullup: true name: "button"</code></pre><p>Simply solder a pin header between D4 and GND to connect your button inbetween. I used these <a href="https://amzn.to/3QOICMS">cheap little wire harnesses that come with plugs</a> that i got with an arcade controller kit.I used <a href="https://amzn.to/3QOICMS">cheap little wire harnesses that come with plugs</a>.</p><p>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.</p>
