This is a simple hobby circuit of Android Controlled Bot usin Adafruit motor Shield & Arduino uno. The main component used here is the Adafruit motor shield, Arduino Uno, Bluetooth & Android device. Using Motor Shield we can drive two DC motors at 64Khz speed and also can controll the speed. Using Arduino Uno & Bluetooth we can controll the DC motors their directions and speed . The advanced of this circuit is PWM speed controll. You must need an Android Device to controll the bot. Below is the total description of this project.

Step 1: Components Needed

1. Arduino Uno

2. Batteries

3. Battery clips

4. RGB LED's

5. Adafruit Motor Shield

6. Bluetooth HC-05

7. 2DC Motors & Chassis

8. Wheels

9. Connectors

10. Buzzer

11. LED's

12. Cable

13. Android Device

14. Female header

Step 2: Assembling and Connections

Place two geared dc motors on chassis fit it with screws, Connect wheels.

My Arduino having male headers so i solderd the female header to connect the adafruit motor shield. If you are using Arduino Uno then no need of female header. Solder the two blocks of female header on motor shield for 5v and gnd for bluetooth module. Connect all the circuit as shown in the ckt diagram .

Step 3: Programming Arduino

First we need to add Adafruit motor Library. Download it from attachment.

Open Arduino IDE>sketches>include library> add zip library > select zip file of motor library.

Upload the code in attachment to your arduino.

Step 4: Installing Android App

Install the Android App.

Pair your HC-05 bluetooth module.

click on bt icon > select HC-05 > wait 3 sec

Click 1 2 3 4 to vary the speed.

Its done!

Start Enjoying!

Where i can find the 5v nd gnd connction on shield for hc-o5?
5v and gnd holes are given on shield. solder the headers and connect it to hc 05 with patch cords.<br>
<p>Can I use Arduino R3 instead of your .</p>
yes u can use arduino r3..
<p>Which arduino are you using, here?</p>
it is clone but same as arduino uno..
<p>Nice share,but where is the app?</p>
<p>Yes, I uploaded .... Thanks!</p>
