ABSTRACT:
A data system and method for entering, storing and displaying a desired digital time which replaces a conventional input keyboard, rotary switch, or thumbwheel switch for a digital timer or clock. This system processes the voltage from a manually positioned wiper of a potentiometer through an inexpensive analog-to-digital converter, displays the digital data to the operator for identification, and holds the data for further processing. The operator repositions the wiper so as to sequentially display a digital time in response to a static or steady state digital signal until the desired digital time is displayed.
