Every Christmas I turn into a child again.
I have a hard time falling asleep. I wake up early in the morning to watch cartoons. And I am probably even more curious about the gifts under the tree than my two-year-old nephew.
I often get emails asking for project ideas.
So I thought I’d share a few Christmas circuit ideas today.
Here we go:
- A circuit that plays a Christmas tune every time someone comes near the Christmas tree
- A line of blinking LED lights of various colors to hang in your window
- An LED-display that can receive Christmas greetings via SMS and show them on the display
- A nut-cracking robot for automatically cracking nuts
- Flickering LED candles
If you build one of them, I would love it if you sent me a picture or short video of it =)
