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
Arduino Duemilanove - $34.99
Ladyada Waveshield Kit - $21.95
2 Super Bright Red LED's - $1.79 for a 2 pack
PIR Sensor Module - $9.99
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.
