Put four red LED as a straight line and connect each of them to a corresponding analog output. Connect a potentiometer to a 5 Volt power source. Divide the 0 to 5 Volt output of the potentiometer into four parts (0 ~ 1.25 Volt, 1.25 to 2.5 Volt, 2.5 to 3.75 volt, and 3.75 to 5 Volt). Write a program to change the brightness of a LED with respect to the voltage. For each 1.25 V interval, the brightness of one LED will be proportional to the output voltage of the connected potentiometer.

There has been no information about related to which programming language is to be used, writing code algorithm.
