Becky Stern’s new Instructables describes how to build a very simple realtime YouTube subscriber counter using a ESP8266 board and a seven segment LED display module.

I was inspired by the Play Button awards YouTube sends out for subscriber milestones and whipped up a simple circuit using an ESP8266 wifi board and seven segment display to show off my realtime subscriber count. This is a great IoT beginner project, with just a little soldering and a code personalization required to make it work for your own account.

Before attempting this project, you should be generally familiar with uploading new programs to your Arduino board and installing code libraries, both of which you can learn for free in my Arduino Class, though you really don’t have to understand any of the actual Arduino code to get this project running.
