The Etch A Sketch: famous, creative, and unique. Unfortunately I have no clue where the one from my childhood is, so I decided to make my own virtual one! Check it out (and my awful drawing skills) below.



This Etch A Sketch is quite like the original, (while it will never replace it, it's still lots of fun) as the analog noise makes the lines a bit squigly like the real thing. The shake to clear is also very entertaining, which only leaves you to make the pleasant "shhk shhk" noise of the sand to complete the experience (definitely necessary, but maybe do this quietly in public to avoid the stares). It's like an Etch A Sketch video game.

This is a fun and simple project (took me 3 hours to write the code, test, and build, so if you have the parts should be ~1 hour) and is a good introduction into potentiometers, accelerometers, arduino, and processing. Anyways, have fun!

Step 1: Parts List

Picture of Parts List
Fortunately, the parts required for this project are simple and cheap. You might even have them all!

Parts:
1 x arduino (any kind of course)
2 x potentiometers (resistance value doesn't matter, mine are 10k ohm)
1 x accelerometer (this is optional, but adds some fun. Mine is only one degree so any will work)
1 x breadboard (not necessarily needed, just makes things easier)
2 x small piece of material approx 5 in by 5 in (wood, cardboard, whatever)
4 x some sort of standoffs for mounting the two pieces of material together
Some lengths of wire to breadboard.
Random tools will also be needed to mount and screw whatever material you're using together.
That is so cool! I can't believe it only took you 3 hours!

Thanks! Hah I was just fortunate that I had all the parts.
