i am a newbie in arduino and want to use a D1804 digital potentiometer on a digital out. as in the arduino samples Analog=>AnalogInOutSerial i connected a potentiometer and LED and it worked fine. but instead of the LED i want to connect the DS1804 which acts then as a potentiometer.
i want to make a little synth like this here:
but replace R1 with this digital potentiometer. anyone could please help me a bit? i have no idea how to use the DS1804, how to wire it?
here is the datasheet:http://datasheets.maxim-ic.com/en/ds/DS1804.pdf
i would use the example code as base for this test. but i might need to add other things like giving an impulse for the direction of the wiper and to activate the DS1804?
thank you very much
