Ultra Long Range Beta Wave Detector

Code

/* CODE for the "Ultra Long Range Beta Wave Detector"
reads value from an analog sensor (0-1023) and maps this to the analog output range (0-255)
to control a vibration motor. at random intervals the sensor values control the speed of the
motor or there is a pause and nothing happens.
