So Halloween is upon us again and I really wanted to use the Arduino I had. I went to the halloween store and found a skull with a hinged skull and that was the spark that began this project. I knew that it would probably be easy to have a servo move using the arduino and have it move the skull jaw up and down.
Step 1: Gather your materials
you'll need stuff. Lots of stuff. Well...not lots of stuff, but stuff from different places. Here's a sort of breakdown of all the stuff I used and where I got it.
2 Super Bright Red LED's - $1.79 for a 2 pack http://www.radioshack.com/product/index.jsp?productId=3096133
PIR Sensor Module - $9.99 http://www.radioshack.com/product/index.jsp?productId=2906724
A small servo - around $13.00 Bought it at a RC hobby shop here in town
A skull - around $9
A black cloak halloween costume - around $10
PVC and fittings - from lowes or home depot
hmmm.....seeing it all written out it seems like more money that I remember spending...haha. Still though, to get animatronic halloween things premade you'd spend a bunch more that that. That's what I'll keep telling myself to justify this.
