What you need is a device that wants the LEDs to turn on one after another when 0~5V comes in. Of course, this can be composed of TR, comparator or OPAMP, but it is not normal to solder 10 comparators... If this is the case, LM3914 seems to be suitable.
There is not much to do. Configure it as shown in the picture above, and when voltage is input through SIG IN, the LED turns on in sequence according to the voltage. It can be turned on one by one, or it can be turned on in the form of a bar.
The sensitivity according to voltage can be adjusted by attaching at least one semi-fixed resistor to the input terminal.
