Power supply Help needed- how to add a 7 segment to display the output voltage

[evilengineer]

Hello Forum

I am 3rd semester Electrical Engineering student , I made a 12 v Regulated DC Power supply as my mini project, now in order to modify it , i want to add a 7 segment to display the voltage which is at output and add a potentiometer to vary the voltage at output and the segemnt display voltage changes accordingly. so how do i do it

There are el-cheapo miniature voltmeter modules with 7-segment LED or LCD display, and all what you have to do is to add a voltage divider to scale the input ..
Here are examples with diagrams:
