I'm new to this, but my teacher already gave us an excersise using the ADC with a voltage range I explain myself (im using MCS9S08LC60 8-bit)
We move the Potentiometer, when it reaches 1.9 (from 0 to 1.9 volts, one led will turn on)
When whe move it to 1.3 (from 1.9 to 0) the same led will turn of)
its not necessary to show the value of the voltage but I don't really know anything, I only know how to make the conversion from ADC to binary the eight leds.
Any info well be apreciated
