After joining to PCB Badge challenge, organized by the Brazillian Computer Engineer and Youtuber Julia, from the channel Laboratório da Julia (Julia's Lab), it was needed to develop a PCB Badge with a Christmas theme. My project idea is to make a simple ornament. Its implementation is made with a Johnson decade counter IC, the CD4017, to create a sequencer. The clock circuitry was made by transistors, creating an Astable Multivibrator.


More about it and a more complete documentation on the Github link.
