We'd like to build a capacitative sensor our of tinfoil, but our backup plan is a Ping ultrasonic sensor.
A couple possible reactions we're thinking of:
- Triggering a vibration motor so the cat shakes
- Red LEDs turn on
Here are a couple sources of inspiration (and code..)
Bare Conductive: Capacitance Sensor
NOTE: If you try this yourself and you use a laptop, make sure your laptop is plugged in so the sensor is grounded! This was very frustrating but now it works like a charm! :)
