When /INC is high, the IC is in the standby mode. The circuit diagram shows a complete digital potentiometer based on a Type X9CMME. It is provided with two controls, S1 and S2, an optical indicator ...

This touch potentiometer circuit has different applications and can be user anywhere ... instead of the touch sensors then place a 1M resistor in serial as shown in the schematic.

Understanding how these components work together is key to understanding electronics. Circuit diagrams use symbols to represent each component, such as resistors, capacitors, transistors ...
