The robot navigates around avoiding obstacles by ultrasound and choosing the best way to follow.

The programming code is attached here as a .txt file. Download it and paste the text on the Arduino compiler.
Remember to add the IRremote library (also attached to this post) to your arduino software before trying to compile the code!

I see another arduino shield above .Can anyone tell me that is, if we have the H bridge below?.Would serve any remote or has to be one specific?. Thanks.

Thank you for sharing . I have got code . But i don't have neither schematic capture nor writing diagram of project . please send it for me .

 My gmail is : timlaibautroi090792@gmail.com

Thank you so much !

I have bought kit, sensor shield is v4.0 , can you please help me in wiring this ? i am really confused and i am very new to this....

i have tried searching on google so far i am not able to figure it out completely. 

please i need help


You may check my wiring in the pictures i posted earlier in this blog. Look for them. Good luck!

Can you please help me in the wiring? and where should i put the ENA & ENB pins? 

i put the wires just like you said, downloaded the IR library and installed it, and uploaded the script. Now all that happens when I press the '1' button is the robot judt keeps moving forward. I tried to move the head thinking that the servo was stuck, but the head (the ultrasonic sensor) would just vibrate in its place. You got any idea about what's happening?

 

Microservo must be connected to pin number 5.. just in case

Check the wiring of the microservo and ensure that you are using the correct pin according to the programming code. 

Sorry if im asking too much, but if you're an expert programmer, please help me with this:

i downloaded a script for arduino: (this is part of it)

#include "Ultrasonic.h"

#include <Servo.h>

#include <Motor.h>

Ultrasonic ultrasonic(12,13); // 12->trig, 13->echo

Servo myservo; // create servo object to control a servo

Motor motor;

 

it's showing me this and not letting me compile:'Ultrasonic' does not name a type

What does this mean? And what should i do to fix it?

The ultrasonic library does not work in arduino 1.0 or above. Either ditch the library entirely (ultrasonics are dead easy to use, no need for library) or use NewPing
