Hello everyone. i am designing an adjustable power supply and in this power supply i am using an arduino with a built in ADC 10 Bits to control a DAC MAX5217 16 BITS. The DAC output will be driving the adjustable pin of a LDO linear regulator. The thing is if i am understanding this correctly. i don't wanna control this through my PC, i wanna control the output voltage of the DAC with my hand. So the question is, i think i can use rotary encoders or 10k Poti right? which POti should i use and where do you connect it? to the arduino or where exactly. The picture is not really clear! Maybe its a newbie question but this is how we learn! i appreciate every answer. Best regards, Fabi

That way you learn the advantages and disadvantages of them. I think encoders are a bit easier to start with. It is a good idea to organise the schematic of your arduino and the data sheet of the microcontroller, which is placed on the arduino.
