Bouncing Betty Halloween Prop. A prop skull mounted with an mbed microcontroller armed to scare anyone who comes close to it. This project uses an infrared sonar, speaker, and, shiftbrite LEDs.
Introduction
This Bouncing Betty Halloween Prop was designed for a haunted house that was built at my university. The skull will sit quietly illuminating between blue and green until guest approaches it. As soon as the infrared proximity sensor detects someone within 40 cm, it will scream and turn red to try to scare guests. A pushbutton was mounted to the skull so that it can be tripped without the sensor. A watchdog timer and power management controls were added to keep the skull up and running.
