Hello people!
The volume goes up and down correctly. The lower the volume, the more noise it produces.
DS1804 has 100 positions:
In positions [80,99] it does not produce noise (I do not hear it)
[70-80) -> produces a little noise
[60-70) -> more noise
[50-60) -> even more noise
...
[10-20) -> a lot of distortion
The component is original purchased from "Mouser Electronic".

I use a constant 5v power supply, I don't use USB-C
I have 2 units of DS1804, they both do the same thing.
<code>
#include <DS1804.h>
#define increment 14
#define select 33
#define up_down 27
// DS1804( byte CSpin, byte INCpin, byte UDpin, unsigned long maxResistance )
DS1804 digipot = DS1804( select, increment, up_down, DS1804_HUNDRED );
void setup() {
Serial.begin(9600);
digipot.setToZero();
}
void loop() {
if ( Serial.available() > 0 ) {
int position = Serial.parseInt();
if (position > 0) {
digipot.setWiperPosition(position);
}
}
}
</code>
Any ideas? Thank you
