This tactile sensor is made of capacitor microphone.
You can make the sensor just by sealing the aperture of the microphone by some thin adhesive tape like Sellotape, in order to cut normal sound.
In this movie, an Arduino captures output voltage of the sensor by A/D converter and then
it applies the A/D value to the lighting strength of a blue LED using analogWrite() function.
This movie is just a test of the behavior of the sensor.

Sorry of low resolution of the movie...
