Thanks to pcbway.com for helping make this video happen!

In addition to this channel, I also run a retro tech channel (youtube.com/pnpretrospective) and I wanted a way to keep track of my subs and views on that channel, in a way that would fit in with its retro feel. And so, the Macintosh Mini Sub Counter was born.

Make sure to select the correct board (I Use ESP8266 generic) and COM port from the Arduino IDE when programming. I didn't touch on this in the video, but figured I should add a note in case this is your first Arduino project.
