Step 4: Testing

     If you followed this tutorial and you got something like in the video below, then, CONGRATULATIONS you have succeeded in making your first LINE FOLLOWER ROBOT.

<p>I have a question regarding the arduino program. I can't get it why are the values for p1 p2 p3 p4 p5 p6 set. I also don't know what are those for. I see that you are using analog sensor. And at last how can I modify the program to use digital sensors.</p>
<p>good bot</p>
<p>Amazing instructable about Line follower robot. I will try to work on this project next week.</p>
<p>is there a site i can buy all the components all once ?</p>
<p>swich on sensor not respond help me</p>
<p>it run streng only not follow line. </p>
<p>I've built this, but without sucess. Did someone managed to get it working?</p><p>If i stick my finger in one of the sensors it does power both motors, but the steering does not react to anything else. Once that sensor goes of motors stop.</p>
<p>cann u send me the eagle.sch and .brd files i want to add some things my email is ptapan268@gmail.com</p>
L14G2??<br>I got L14G2. It is 3 terminal photo transistor....<br>Which photo diode did you use???
u can send it to me? please. <br>i really need this circuit :) <br>mail: linhpiorey@gmail.com
bro i think #nbinest is not gonna reply for our queries soon enough...........so i think it will be better for u to search the internet..... <br> <br>i am also into making of this one....till now i have found everything i need to make this one just by surfing the net .....:) but still have many questions left to ask #nbibest&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;:(
how can i make this robot follow white lines on black background? <br> <br>adi.sreyaj@gmail.com
Dear sir, i am school student.i am using atmega 328 ic.programme with arduino uno.sir Robot not working.Sir please worked arduino uno programme file. <br> <br>my e-mail - fast.aruna@gmail.com <br> <br>Sir please reply urgently....
Hello could you please tel whether i can use this http://www.electroncomponents.com/Integrated-Circuits/Microcontroller/Atmega168A-20PU-Microcontroller <br> <br>or should i use this <br> <br>http://www.electroncomponents.com/Integrated-Circuits/Microcontroller/Atmega328P-PU-Microcontroller <br> <br>Please answer quickly thank you
Well... you need to have a microcontroller that is compatible with arduino. One of the microcontrolers that are used in arduino. I think atmega328 is used in Arduino Uno maybe?
u can make a good design...
what is the program you used to draw the pcb ? <br>Do you have the C or assembly code(for understanding the code) other than hex for atemega 8?
Plzz tell me about its programing and also pcb!
thanks for such good i'ble, Please put the PCB layout for us to diy
plzzzz send me high speed line follower robot details like circuit diagram,component,etc.
Here. Everything you need. <br>http://dl.dropbox.com/u/16925058/Line%20Follower%20v2.rar
Hello, thank you for your interest in my robot. And sorry for the late answer. <br> <br>J5 and J6 is just a switch. J7 is used for connecting to battery, so when J5 is not shorted to J6, the circuit is open and the robot is stopped.
in the circuit diagram explain the terminals j5,j6 etc
Have a look at a new concept - A wall follower robot <br> <br>http://www.geniusdevils.com/2013/01/wall-follower-robot-with-distance-sensor-and-microcontroller.html
If i want to use arduino for this, how will the schematic change please tell
well done
how are those components connected on the PCB layout. it will be great if its visible. tnx
Why do you use the 6-pin SIL in the circuit?
It's for programming. I have built an USBasp programmer and that's my &quot;standard&quot; for programming :D
k..den i wont hav that in my circuit..coz i wanna keep it simple.. <br>Bro.. it would be nice if you send me the schematic for the sensor too..coz i wanna make some modifications...nd u hav only uploaded the design <br>you can upload it here or mail it to me at <br>sureshv2212@gmail.com. Thanks.
plsssssssss can i have the connecting circuit diagrme. send it to me. <br> <br>EMAIL: canutemark123@gmail.com <br> <br>
can u please give me the circuit diagrame. plsssssssssssssssssss. im still a kid
I have make this project through your guidance just what to know what was your <br>ir sensor reading on black and white line mine was approx 2v on shinny black and 4.6 volt on shinny white what distance you keep from surface to sensors.also what rpm of motor do you use?<br><br>ALSO please tell what does variable nr do in your program?<br><br>EMAIL:muhammadrohaan@hotmail.com
