1. A handheld device for randomly selecting at least one number, comprising:

  • a sensor for detecting a variable biometric parameter of a user in proximity to said sensor and outputting an electrical signal that varies based on said variable biometric parameter;

    a square wave oscillator for providing an output signal having a base frequency, wherein said oscillator is connected to said sensor so that said base frequency is modulated by said variable electrical signal;

    a microcontroller coupled to said oscillator to receive said output signal at a clock input of said microcontroller, wherein said microcontroller is programmed to increment through a sequence of numbers at a rate determined by said output signal.
