Grid follower robot(analog sensors and digital sensors)? Answered
OK first of all I am under time constraint (just 4 days to make a grid follower)
Ok I have built a line follower before (two ir sensors and arduino),
So now the problem is ,we have two sensors which we have made using ir emmiters and sensors (which work as analog ,ie no relay)
We have now purchased two IR modules which has got a relay giving it a digital output.
So I am asking how we should place these sensors to get the least wobling and correct 90deg turns
