PCB Pyramid
In this project I built a rather interesting project which I thought a long time ago. Its basically a 3D sculpture using PCBs. Here I built a Pyramid. I also included some WS2812B LEDs and a ESP8266 to control them over wifi using Blynk IOT platform.
Construction :
we need 4 of this to create all four sides of a square pyramid. Each side of the pyramid consists of 10 WS2812B addressable RGB LEDs. I put an ESP-12f on the backside of RGB Pyramid PCB. Though I only need to do this once. As the other boards will be connected with this one in series. Why ESP -12f you might ask.
Controller :
Well, there is no particular reason to use an Esp8266 for this project. Any microcontroller even an Attiny would work just fine since I just need to display some patterns. But I use it so that I could connect it to WiFi and control is over the internet. The obvious choice comes to mind is the WS2812FX library. But I wanted to have more customization solution.
BLYNK Integration :
So I have used Blynk IOT Platform for this. So I make some bits any bytes and include popular @blynk.iot platform on the project. So now my Pyramid can be controllable OTA. I'm still using the WS2812B library to drive the LEDs but also making some custom effects for it. About the App - there's a zeRGBa colour picker to choose any static colour, Two sliders. One is for controlling the brightness of the LEDs and the another one is for changing the speed of the effects. And a button to change between different modes.
