Hi everyone, I´m new here, first of all, I have to say that this an awesome forum, I have found a lot of information that I can use to create my project that I cannot find somewhere else. I am from Spain, so sorry if I make some mistakes.
So let me explain you what I want to do. I have no knowledge of electronics, that´s why I need help. I want to make a mas like This , but for my own and with another design, I have found some info in this forum that helped me to make a scheme of what I want to do to show you, I will put a image on the post to show.
My idea is to connect 5M of WS2812 Leds using an Arduino UNO, with a 20.000 MAh PowerBank, and control the leds using an APP on an Android Phone, using HC-05/HC-06 or HC-10 BLE (don´t know which one is better for my project, if you can recommend me one will appreciate :) ). I will put a photo so you can tell me if I am going in a good way with the circuit, and how can I connect the bluetooth module as the same time as the leds on the Arduino.
Thank you for your time, and if you want to help me, just leave a comment :).
PD: There is a mistake on the photo, the modules are HC, not HM
Hi EdwardC,
sorry for the late response and thank you for the compliments ... 
I'm not familiar (yet) with the HM-modules you're using. However the wiring of the Arduino, LEDs and powerbank seem correct to me.
While looking for HM-module information, I did find this seemingly very good post on how to connect them to your Arduino. Hope this helps
