 * In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a "trigger" because the output retains its value until the input changes sufficiently to trigger a change (wikipedia B).
+* CASCADE module: frequency divider. a circuit that takes an input signal of a frequency and generates an output signal of a frequency: f(out)=f(in)/n where n is is an integer. Within the modul the integer is 2, 4, 8, 16, 32, 64, 128, 256, 512, and 1024.
+* CELL-AMP module is an arduino-type transducer converting analog signal into serial.
+* PWM or Pulse-width modulation is a modulation technique used to encode a message into a pulsing signal, eg for getting analog results with digital means. "Digital control is used to create a square wave, a signal switched between on and off. This on-off pattern can simulate voltages in between full on (5 Volts) and off (0 Volts) by changing the portion of the time the signal spends on versus the time that the signal spends off. The duration of "on time" is called the pulse width" (arduino).
