Introduction: Christmas Tree PCB
Instead of buying a generic Christmas present I created this small Christmas tree out of PCBs and added these lovely RGB LEDs that fade out into different colors.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Design and Order
This Christmas tree is designed as a three PCB's soldered vertically one to another. There are no 3D printed parts or extra DIY parts, all you need is PCB's that you order, SMT components and a soldering iron.
Christmas tree consists of 20x 0805 LED spots that you can mount all kinds of LEDs. Blinking ones, fade-in out, programmable, etc..
To power the device I use two CR2032 batteries. Every LED is paired with one resistor, choosing a higher value resistor will dim the lights but extend the battery life. Here I provided you with a list of every component used in this build.
Step 2: Results
