This is a lower-cost version of my Touch Potentiometer without the AD5262 chip. It is designed for use in digital applications such as LED dimming using the PWM output or as a computer or micro-controller peripheral using the serial or I2C interfaces. It doesn't have the analog pot functionality (although the user could add a AD5262 and supporting bypass caps themselves). This version also has very cool white LEDs.
Example code for arduino, circuit ideas and the "tputil" program used to configure the Touch Potentiometer can all be found on my website accessed through the Documentation link.
