Bluetooth Controlled Robot With Spy Wireless Camera

In this instructables i will show you how to make wireless robot controlled with Bluetooth module.the best feature of this robot is wireless camera working over wiffi.in above picture you can see my phone working as camera.my phone is connected to home wiffi and the Android app named AirDroid is used for Wireless camera.

for remote control over Bluetooth i have used this application Bluetooth Electronics

Step 1: Components Required

1.arduino uno

2.bluetooth module hc-05

3. DC Motors (4)

4.Robot base

5.motor driver l293d

6.android phone

7.12v battery

8.ultrasonic sensor hc sr-04

9.jumper wire's

Step 2: Schematics

as shown in have connected two Dc Motors in parallel combination for turning the robot.for turning to right. left side Motors will be on and for turning left. right side motors will be on.
connect ultrasonic sensor vcc pin to digital pin 12
trigger to pin 8
echo to pin 9.
connect tx of arduino to rx of Bluetooth module and rx of arduino to tx of Bluetooth module.
During uploading the program disconnect Bluetooth module.
as shown in figure for running Dc Motors supply external 12v power supply.
for arduino you can use regulated 5v supply but i have used Mobile phone otg power supply.
And i have used 12 v battery for running motors only.

Step 3: Arduino Programming

I have uploaded arduino program file.you can edit it according to your requirement.in this program i have used millis function instead of delay.when i used delay function it stopping all the program.this program is combination of two program one for motor driver and other for ultrasonic sensor.

for running millis function you have to install libraries. i have uploaded zip file. extract it and paste it into libraries folder of arduino ide.

Step 4: Configuring Android App

Download Bluetooth Electronics app from google play store
I have uploaded my kwl file of panel.you can import it as shown.you can edit it according to your requirement.

Step 5: Configuring Wireless Camera

Download AirDroid app from google play store.connect your phone to your home Wifi then enter above ip address shown in app. on other browser of other device connected on same network. click on camera icon shown in picture.you can see live streaming.

Where is connected a otg cabal

[NishanthM4]

rather than using my phone can't i use a wireless wifi controlled camera like the one's available on amazon and can u share with me all the information of the project i would like to do it.You can mail me at [e-mail] . I would really like to hear from you

[YuvrajJ3]

Sir please tell me IN AIRDROID APP WITH PICTURE STREAMING AUDIO WILL BE THERE??

[Kumar Shiva]

in which version of the airdroid the camera can be accessed

[Kumar Shiva]

give us the version of airdroid to be used

[Kumar Shiva]

how to link the arduino program with arduino board which u have given

[Kumar Shiva]

Sir,we have taken your project from instructables and we have completed half of it.We are getting defects on the motor driver and we have already lost two boards.So please give us the connection of the motor driver to motors and arduino.

[SprasanthKumar]

sir,here in #include <elapsedmillis.h> its showing error what should do

how to connect mobile with arduino ?

[kathait]

Did this also avoid obstacles

[Aadarshsrivas]

Can we use hc08 instead of hc05

[saurabh47]

I haven't hc08 .i don't know.
Try my code.if this works for hc08 late me know.

[Aadarshsrivas]

ok

thanx for reply

/*try this code.

i am also getting same error on arduino IDE 1.6.12.

which version of arduino IDE are you using??

use 1.6.5 version of arduino IDE*/

[Kamal rjn]

help me bro pls

[saurabh47]

I think now problem is your arduino.please try to upload simple code like blinking LED and if you succeed then try my code.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with

"Show verbose output during compilation"

enabled in File > Preferences.

[saurabh47]

are you able to compile the code ??
i think now the issue is due to the drivers or your arduino is not working properly.
install drivers properly .
