Hi! I'm sorry for my bad english

I need a programmable power supply for my home lab but can't find a project. I search something like this.

Can you help me?

 

Hi,
Not exactly what you need, but you can use an LM317 for that without display. Take a look at:

Hope this helps.
Tahmid.

 

10x something complexity.. with display and microcontroler ?
