This project is so easy to build.
Using the ESP8266 WiFi module can connect to the internet. Once connected, using the YouTube channel ID and the API key we obtain the YouTube subscribers count and then we print that value to a 7 segments screen module.
All we need is a PCB ordered from PCBWAY, WiFi module Wemos ESP8266 and a 7 segment display to print the values. The code refresh it self and it will beep each time the value changes.To make it look nice, I’ve red 3D printed the youtube icon.
