Q: I tried to use it in a line follower. kept it 1cm above ground(resistor at receiver is 4.7k).At white & black surface it gives ADC value 185 &65 respectively(10 bit/0-1023 range). Is there a effective way to increase the difference. Questioned by khaledeeebuet, 02-Jul-2013

You can use a comparator IC. Answered by A.R, 02-Jul-2013 10:11 AM

u can also use higher resistor (i.e 100k or above) if that is a voltage divider circuit.That would give u better difference.although,op amp is better to avoid loading error Answered by abushuvom, 19-Sep-2013 16:13 PM
