View Full Version : Uc Less line follower

06-12-2008, 12:14 PM
The line follower mentioned in the first look section has no circuit digram for connecting the sensors
plz kindly provide me with the circuit digram for interfacing the sensors with motors via L293D
not with other motor drivers
i want to do it with L293D
thanking you

Really Sorry about the uC Less article, the files were deleted on the server, I have a copy of the page and I am in the process of acquiring them. The schematics will be up again in a week

can u kindly send a pic of that circuit to chinnikrishna.ece@gmail.com
i badly need that pic as everything came to a standstill due to unavailabilityof tat pic
we are done with sensors chasis everything
plz kindly help us

sir the schematics are still not visible..

the best way is to read digital logic desingng its very easy u need to study abt .............a comparator,or-gate,and-gate,not-gate,l293d, thats enough to make a line tracer with out a microcontroller

Are yaar, microcontroller less Line follower is very easy.

You will just need NAND, OR, XOR, NOR gates (total Less than 10) for 3 to 5 IR pairs used

I will suggest you people to design yourself & ask in case of any problem, I will surely help you.

I am telling you because it is really easy, & need to know only Truth table of above gates. thats it

is that true, that it is possible to build a line folllower with some basic logic gates....
plz explain...... 8O
