Instead of controlling the LED brightnes one of the Digipots are used to control the volume of a speaker being driven with a square wave from pin 8 on the Arduino. The square wave frequency is also varied using the tone function.

Thanks for the nice presentation. It was very informative. Can you please help me with the similar Digipot (MCP41HV51). I have MCP41HV51, which I want to use for high voltage applications. Can you please upload a video for using arduino with this Digipot. Thanks in advance.

how to set digital potentiometer to a fix resistance value

Hi That's really interesting. If I understand it the LEDs are cycling through a sequence where the digipot, through the controller, offers less and less resistance creating the brightness swell. Could an arduino/digipot be used in a similar way to control a digipot in a guitar pedal that would increase or decrease the volume of an audio signal over a given time to create a uniform fade in? Do the increases have to come in discrete steps or would it be possible to have the increase have a logatithmic increment over time to replicate an audio/logaritmic potentimeter?
