Hello i am new to arduino , and i am trying to learn how to use it : :) :)
I am currently working on a project where i need to drive an outuput voltage of 12v to a heater, but i want to use a power supply .. that \ can manually change the values of the output
I also have in my mind an idea of using a rotary encoder or a potentiometer to change the output voltage in order to to change the heating .
But again also want to use a power supply to see how it works.
Do you have an idea of which power supply i can use
And please can you tell me if my point of using a rotary encoder or potentiometer would be accurate
