Hi all,
I put together a Spark Halloween project this weekend. I tried to do blinking pumpkin last weekend but my pumpkin was eaten, and thus I made a a motion sensor-buzzer alert system to keep squirrels away from my pumpkin, and, you know, to tweet.
It’s the first time I’ve used Instructables but it was really pretty fun!! Special thank you to @middleca for being a huge help on getting this put together 
I even managed to capture a squirrel getting buzzed away…
Enjoy! http://www.instructables.com/id/The-JackO-Lantern-Early-Warning-System/
