Hi all, I have plan to make adjustable power supply and I want to control it with rotary encoder. I am new to all this but so far I think I need x9c103 module from aliexpress, 1 rotary encoder from ali, 1 arduino nano. For voltage regulation I would use XL4015 board from china with current and voltage control. Later I would add 1602 lcd to display voltage and current values.
I need someone to correct me if Im wrong, On xl4015 board voltage is controled by 10k pot, x9c103 is 10k digital pot so i think it will be ok. Now im confused how to pick rotary encoder, does encoders have to match digital pot. value or any rotary enc. from aliexpress will work?
I put small illustration how i want to connect digital pot to regulator board, you tell me please is it correct way.
