Insult Your Neighbors This Christmas With Arduino

Last December I was kind of pissed of at my neightbors so I wired my Chistmas lights to blink an insulting phrase in Morse Code . I was sure nobody would notice but doing it made me happy nevertheless.

Yesterday I posted about it in reddit.com (link ) and so much people approved that I had to show how I did it. Electronics and Arduino people will know the circuit is very simple. As always, take care to not zap, fry or shock anything.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Choose the Lights Type and Adequate Circuit

I live in an apartment so these LED strips were enough to decorate a window. The LED strip is 12V, so I used a TIP 120 (or 122). There's no need to describe my circuit because there's already an Instructable for that:

Instructable: Use Arduino with TIP120 transistor to control motors and high power devices


NOTE: If you use incandescent lightbulbs, know that's more Volts, more Watts, more Amperes and this circuit won't work. In this case do research on circuits that use a a relay or TRIAC or SCR. I repeat the warning: don't fry, shock or kill yourself.

Step 2: Program Your Arduino With Insults

Here's the code I used. Feel free to use, modify and distribute, I don't care.

Step 3: Final Thoughts

I can't think of anything right now, but I'm sure someone will make a comment somewhere. Or maybe not. Merry Chistmas, you $&}#z*p%*s!

    nice! :) if you want to switch more than one strip you might want to look at a Darlington array ic like an ULN2003
