How to design a current and voltage regulated supply with digital display?

Question

Please send me its full description...

Answer 1

I have built both voltage and current supplies that are regulated. However, it will be very difficult to explain this to you without drawings. So go to an IC supplier and buy a LM338 chip and they will give you a circuit diagram that will explain everything. It is very easy to build. There are other ICs that work just as well.

Answer 2

Decide on voltage and current range, then start searching for a design.

Much too difficult to describe. I don't know of an IC that will do this, you will need to use power transistors, zener reference, and several opamps.
