“I will honor Christmas in my heart, and try to keep it all the year.” ~Charles Dickens
This year I fashioned a Christmas tree decoration using LEDs, 200 ohm resistors, breadboard and Arduino Uno. I hope you find this project interesting and let the Christmas mood get into your heart.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: Schematics
First LED construction will be multiplied by 3, because we have a Christmas tree with 3 identical parts (component wiring except dimensions).
For the second construction we have 2 RGB LEDs connected in parallel.
The OUTPUT pins are connected to Arduino Uno.
Step 2: Step 2: Construction
I used a gift box for the base of tree and a wooden plank for supporting LEDs.
Step 3: Step 3: Arduino Code
I programmed the LEDs to light the Morse message "HAPPY NEW YEAR"
Step 4: Step 4: Demo
Hope you enjoy this project!
