Electronic potentiometer system has pushbutton interface:  09/26/02  EDN - Design Ideas / (Electronic circuit added 10/03)    As systems grow smaller, it becomes increasingly attractive to replace mechanical potentiometers with electronic potentiometers, which are smaller and less expensive silicon equivalents. A common interface for such devices comprises a Chip-Select, Increment and, Up/ line. CS activates the device and, on a rising edge of steps the wiper in a direction that the U/ pin indicates..

LED dimmer uses only two lines:  03/21/02 EDN-Design Ideas / (added 06/03) This circuit provides32 steps of brightness control (from0 to100%) for a backlight or instrument panel, using just two general-purpose-microprocessor signals.  Although the circuit shows the circuit driving white LEDs, the load could also be a dc motor or an incandescent lamp. The basis of the circuit is a modified Schmitt-trigger relaxation oscillator controlled by MAX5160 digital potentiometer.

Linear Potentiometer implements Logarithmic Gain Control:  10/23/97 EDN-Design Ideas / (Electronic Circuit diagram added 03/03)   -- Trimmer potentiometers are ubiquitous components and are available in a variety of packages, Resolutions, and temperature stabilities but none of these potentiometers implements anything but the usual linear function of resistance vs. shaft position as useful in many audio applications
