Change the brightness of the most beneficial illuminated LED to represent voltages among the ranges so that if the value is half way among the range then the LED should be 50% brightness. This can be achieved by using Pulse Width Modulation (PWM) ie. Turn the LED ON for 50% of the time and OFF for 50% of the time will.
