Any New Year’s party is incomplete without some sort of countdown to welcome in the new year! Although you could easily use an app on your phone, nothing beats the satisfaction of making your own! This is exactly what The Soldering Station has done using a seven segment display and an Arduino Uno.
The instructions are very thorough so you should have no trouble getting your countdown timer ready in time for the 31st of December! To get started checkout the following link. You can see the kit in action in the video below.
