Post Body

check out the album here

First i set up the arduino to parse the incoming serial data to find a key word and then parse ints to set the RGB values of a Neopixel strip.

Next i added in the wifi chip, which after set up just prints all commands you send straight into the UART so the color changing code didn't need any modification. That is one of the reasons i like the esp8266 its very easy to get the data off of it.

Finally, I set up a python webserver that will serve up the HTML / javascript color picker to the browser. It also parses the input color and opens up a TCP socket to send the data to the wifi chip.

I loaded up the code onto github if anyone wants to try it.

EDIT:

added a schematic
