ESP8266 and the new wifi things revolution

Recently I bought a Huzzah Breakout board based on ESP8266 from Adafruit. Really nice piece of technology similar to an arduino or a Teensy development board... but with Wifi capabilities!. Isn´ t that gourgeous?

This tiny wifi enabled micro has some amazing features:

• 1 x Analog input (1.8V max)
• 9 x GPIO (3.3V logic), which can also be used for I2C or SPI
• 2 x UART pins
• 2 x 3-6V power inputs, reset, enable, LDO-disable, 3.3V output

You can program the little beast using a preloaded Lua Interpreter, or with Arduino IDE, or even with microPython... but this last does not leave much memory to be creative... so I decided to program it using arduino programming lenguage, which is pretty good and stable, using tons of arduino libs for doing whatever the imagination is able to give us.

So, I decided to create a very interesting combination:

Hardware

• 1x Huzzah Breakout Board
• 1x MCP23017 16-bit port expander using I2C interface
• 2x SainSmart 8-channel relay board
• Raspberry Pi 2 or 3

Software

• Socket Server using python (running on a raspberry pi)
• Web Application using flask and python (running on a raspberry pi)

The Idea is to create a 16-way channel relay box wifi enabled to be manipulated trough a web app, that can be used from any device.

Stay Tuned...
