• Description:
In this video, I go over the process of building a Data Visualization display using a Raspberry Pi and a 7-inch Touchscreen Display. I show, step-by-step, the assembly of the hardware as well as the necessary software for having the Raspberry Pi run a fullscreen webpage right after booting up. I also detail a custom webpage that uses JavaScript and the Google Charts API to plot data. Lastly, I outline the code in a Python script for querying an API in order to fetch the data needed to generate the visualizations.

As an example, I use the messages to control a couple of 8-pixel WS2812B LED sticks connected to the ESP32. I expect the messages to be formatted in a certain way using JSON formatting. The code will be running live at: https://www.twitch.tv/acrobotik For usage, copy paste the message in the line below: !{led:X,R,G,B} And change X to a number between 0~15 (pixel #) and R/G/B to a number between 0~255. • Related vids: Getting started with the ESP32 using Arduino: https://youtu.be/-P7RD-DWVuA Getting started with Websockets: https://youtu.be/ROeT-gyYZfw • Project parts: ACROBOTIC Development Boards for ESP32: https://amzn.to/2D3KiA6 (affiliate) https://amzn.to/303INZK (affiliate) https://acrobotic.com/products/acr-00024 ACROBOTIC WS2812B NeoPixel LED Stick: https://amzn.to/3dbg2Bs (affiliate) https://acrobotic.com/products/led-00042 ACROBOTIC WeMos Proto Shield: https://amzn.to/2PBK2KE (affiliate) https://acrobotic.com/products/acr-00009 • Project code: Firmware for the Arduino IDE: https://github.com/acrobotic/Ai_Demos_ESP32/tree/master/twitch_chat_ws2812b • Sponsor: This video was sponsored by PCBWay • Music: YouTube Audio Library #ESP32 #Twitch #Websockets$
