A simple mktwo-badge hello world app.

The mktwo-badge is something I picked up at Penguicon 2017. It is a ESP8266/WS2812 wifi-enabled badge with Arduino-compatible pin-outs.
You can find out more about All Hands Active and the mktwo-badge here.

This program is a very stripped down "Hello World" web page hosted on the badge. The ESP8266 web server has a default IP address of 192.168.4.1. The SSID is set to "ESP_" following by the last 6 bytes of MAC address.

You can use the Arduino IDE. It's not the most user friendly environment, but it's the least painful to setup. I use Visual Studio Code with the Arduino Extension. This still requires the Arduino IDE, and unfortunatly, at this time, the Arduino Extension does not work fully with the portable installation of the Arduino IDE.
