Arduino Nano, HC-05 bluetooth module, and some super bright RGB LEDs!

This project should be fairly straightforward. I plan to turn the results into a youtube tutorial. The costs are minimal and the know-how is basic.
I'm a teacher at heart- so I like to give back to the community that taught me!
I'll also whip up an ESP8266 version, using NodeMCU and espruino.
I still need to refactor this entire thing- but hey, it's working! I'd like to figure out TABS in Android Studio so that I can dedicate more screen space to settings and sliders. Right now everything is stupidly cramped into one screen. 
Friend of mine who started me on this RGB journey got a copy of both the Arduino and Android code. He's planning something with more LEDs with transistors and whatnot- using my code to get started.
I'm looking forward to seeing what he puts together.
I have a 16ft RGB LED strip in my living room, and I think it would be nice to use this as a controller. I can never find the remote!
Figured out how to do constraints with a bunch of trial and error..
The UI editor drag-n-drop animations are super laggy and buggy. Undo feels wonky too. At least things are progressing along.
Color Wheel looks fancy- but the simple RGB sliders are easier to dial in to exact values. I think I might end up liking Android Studio after I get used to the tools.
Well I spent probably too much time soldering on my first set of headers. In comparison to some of the youtubers who got me interested in soldering - I did a poor job.
I accidentally bought some very thick solder. I spent most of my time wicking it off!
Also, I need to get some blue-tack or something to hold the headers in place.... Hot glue was a poor choice...
(I'm a software guy stop laughing!)
But hey- the connections are electrically sound! So I'm happy with it!
I wish I could tell you that I waited for the long boat from China - but I picked up 100 of these LEDs from Amazon.

There is a resistor on the red leg, as it is only 2.2v tolerant. The other channels are running off 3.3v (which is overdriving them just a little bit!)
EDIT: Yes - I'd say they compare pretty well to some NeoPixels! They don't look as cool though.

Where are you sourcing the super-bright LEDs? And how do they compare to the bright neopixels? Also, I didn't notice any resistors in your screenshots or component list - most LEDs will burn out after prolonged use without a resistor to limit current.
