Hi y'all!! This is my second post
Well i finally got down to building a line follower and worked on it for two weeks non stop. Made a pretty neat analog logic unit(using gates, k maps etal) and in the initial stages(breadboard) the sensor arrangement(LED+LDR) had given a good resolution between white and black but on the day we assembled everything onto the body whoosh no resolution!!
Then we moved onto ir led+reciever arrangement and made it exactly according to data at
http://www.roboticsindia.com/modules.php?name=News&file=article&sid=71 but it also didnt work for some strange reason then in a last ditch attempt we resorted to reflective modules(on2509) but they seemed to work only at a particular distance from the surface and such an arrangement isnt possible on our chassis.And so my line follower is stalled for the moment!!
Guys i need some serious help quickly with regards to this.Thanks in advance!!
