This project probably has the most parts of any of the ones we have done, but is sure to help spread some Christmas joy. It’s a clock which displays the time and date, and also displays the number of days until Christmas. When the sound module is triggered, a voice (it might be Santa) announces the number of days and weeks until Christmas and then offers a Christmassy greeting. It’s sure to keep everyone entertained. There is some soldering and careful assembly required to compete this project.
