A Lipo charger and protection circuit, a boost converter, a bunch of WS2812b and an ATMega328p - All of this makes a circuit forremote operating LEDS.
The circuit include a header to plug a RF module (nRF24 ?).
The ATMega is used with it's own internal oscillator (not precise 8MHz), but it's sufficient enough to drive this small circuit.

*ESP8266 and WS2812b Individually Addressable RGB LEDs [12 bit]*
**EspRing** is a 12 bit neopixel ring using **ws2812b** RGB LEDs and to control the LEDs there is an **ESP 12E** module builtin. So basically you'll get a *neopixel ring which has a onboard microcontroller*. Since WS2812B leds are individually addressable so we just need only one data pin from the microcontroller along with VCC and...

I designed this PCB to be used with a project from Instructables to build a sound reactive lamp. Take a look at the project if you want to build it for yourself: https://www.instructables.com/id/Wireless-Music-Reactive-Floor-Lamps/
As you see in the linked project, i changed the schematic a bit. I've added the sound detector to the lamp pcb...
Simple module for creating your own led lamp. You can use RGB strip, WS2812b, one-color strip or others.
