  I've created a new thread with your post.

  lets start robotic:
  
  as i have seen in forum under robotic there is given an article related to laws of robotic and other stuff which i find quite annoying so to start up i would like you to see "ROBOT" film by rajnikant and it explain the required .
  
  since we all are engineer and are people who take thing in a different manner therefore, i am also going to explain the stuff in a different and interesting manner.
  
  so the objective is to make a line follower robot :
  the robot which will follow a line and that line can be straight , curved or circular or of an other form but robot has to follow that line .
  
  
  so uC is atmega16 , please go thru the data sheet of uC which is easily available of net.
  just google "datasheet of atmega16".
  download that and see the page number 2 , it has the pin configuration of it.
  the pins and the port a is used for taking in any analogue input form outside to the uC .
  
  port a has 8 pins so max. 8 inputs can be used for analog input.
  
  interfacing :
  
  the ir sensor need 2 pins
  1) signal
  2)ground
  
  so make the configuration.
  
  so that one is connected to uC (port a) and another to ground.
  
  
  on completing it you would have successfully completed the interfacing of sensor.
  
  
  post any question u have regarding the above .
  
  if not i will go ahead and explain the next topic.
  
  
  
  
  
  
  
  
  
  thanks and regards,

  @alikamu: Nicely explained. Thanks for making it simple.
  Waiting for the next part.

  Good going.
  
  It would be better if you can supply some pictures along with the tutorial.
  
  Some simple circuit diagrams etc..

  ok...that a good point ...i will try and post some pics too.:grin:

  thanks for the response ...but i would like to update in the sensor part:
  
  i have today seen an ir sensor which is having 3 connection...in case any one out there also find it ...so here is the interfacing:
  1)input of sensor
  2)ground
  3)input from sensor to the uC.
  
  hope it help the engineers .....

  so friends here is the second installment :
  interfacing motor driving ic and uC
  
  google " L293d datasheet" and i hope you have the uC datasheet as well.
  
  so here is the interfacing :
  
  pins of l293d:
  
  enable 1->connect to any port pin which you want like PD5
  input 1->connect to uC pin like PC0
  output 1->connect to uC pin like PC1
  ground ->connect to commonsense
  ground->connect to commonsense
  output2->connect to uC pin like PC2
  input 2->connect to uC pin like PC3
  Vs-> direct power supply (unregulated) generally 12 v
  enable 2->connect to any port pin which you want like PD6
  input 3->connect to uC pin like PC4
  output 3->connect to uC pin like PC5
  ground->connect to commonsense
  ground->connect to commonsense
  output 4->connect to uC pin like PC6
  input 4->connect to uC pin like PC7
  Vss->regulated power supply generally 5V
  
  this ic can drive a max of 4 motors.
  
  note: u have to send a signal yourself to enable pins. so that the motor signal is passed successfully to the motor.
  
  
  i think it is information that u want to know, please be free to ask the question as a friend.
  
  thanks and regards
