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 

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

Yes. Maybe, you like to implement both solutions. 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.
