Hello! I want to use 4 digital potentiometers and bluetooth HC-05 for my bachelor's degree project. I`m just wondering if it can be done and some advice how to would be welcome! I want to control via bluetooth and arduino 4 potentiometers to set the value of the resistance of an LM1036N basic schematic that controls bass/treble/balance and volume via bluetooth. Thank you, and waiting for replies!
Why digital pots. Real pots were used to make a control voltage.
In the digital world a control voltage can be made directly with a D/A converter.
Leo..

Yes but it hinges on the the schematic that controls bass/treble/balance and volume. These sort of pots are normally only good for about 5mA wiper current maximum, and I would restrict it to no more than 2.5mA.
