oh no, a BAT!

Project Members: 


* Vampire Bat!
* I made a bat that sleeps in the dark. When you expose it to light, it SCREAMS and its eyes FLASH,
* horrifying all nearby. Fortunately, the bat is susceptible to a wooden stake in the heart, as it
* is a vampire. But don't let it lull you into a feeling of safety, if it is allowed to return to
* darkness, it will re-capture its evil life-force and awake again!!
* This program does nothing while the photo-resistor is in the dark. Once the sensor detects light,
* the program will blink the LED (I made two in series to simulate eyes) and beep the piezospeaker
* repeatedly in a terrifying way, until the FSR is hit. Then upon re-entering darkness, the program
* resets its state, waiting to be activated again.
