HUZZAH ESP-8266 (by ADAFRUIT): How to use with the ARDUINO R3
Ok, I'll keep this post open for anyone who got this board and the Arduino and wanted to use them together (it's probably only me, but who cares). Anyway, when looking at this board it's basically it's own controller. The front pins are what you need to communicate with the board itself. It's meant to be used with a FTDI cable to the computer. Anyway, looking further into it we see many pins behind the first 6 or so. To connect it to the computer using the Arduino you need to use this config.

Arduino | HUZZAH ESP8266
RX | RX (In the front)
TX | TX (In the front)
5V | V+ (In the front)
GND | GND (In the front)


Also, you need to create a thing where the Arduino won't be able to function, making it a communicator port for the HUZZAH itself. To do this simply take one of the GND pins on the Arduino and connect it to the RESET pin on the Arduino. After doing this you need to set up your ESP8266. This is a link to a basic guide on how to do this by ADAFRUIT. Instead of the USB cable, you are using your arduino as a cable essentially (a pretty expensive one). Anyway, the port number should be the port that your arduino is connected to (to the computer). This is if you want to use the ARDUINO IDE.

To use NODEMCU LUA which it comes preloaded with, you need to refer to this guide.

The other thing I wanted to mention was how to utilise a basic board with the controller. I had to use a MFRC522 RFID board with the Arduino, and I wanted to send the info to the internet. Sadly, it seemed as if I couldn't use the arduino itself. To use this board I used many sources. First, was the library github (this one).

The next step was to get the pin layout (from here). However, if you look at it it's in the pin format of a WESMOS D1 MINI board. The final source was to look at the product page (here) and convert the pin format to fit the HUZZAH Board (It's in the PIN section). That took a long time, but now you're done. That's a basic guide on how I used the HUZZAH Board with my arduino.
