Introduction: BLUETOOTH CONTROLLED CAR/CHAIR..

Picture of BLUETOOTH CONTROLLED CAR/CHAIR..

Hi everyone...placing my first instructable....

this instructable for beginers who want to control a bluetooth controlled car...the advantage of this car is it would be huge and you can place a chair or any favourable structure on it based on your wish....

i ensure you that this project would be easy/....

the things required for the breadboard circuit are:

1// 1x arduino uno.

2// hc-05 bluetooth module

BLUETOOTH CONTROLLER app from playstore

3// l293d motor driver chip.

4// 2 x 12v motor with 1000rpm

5// 12v battery(rechargable)

6// 9v battery

7// 1x IC 7805 regulator

8// connecting wires

------------------------------------------------------------------

things required for the model :

1// a wooden board (any size based on your requirement)

2// 2x wheels for the motor.(width must be greater)

3// 4 x rolling wheels(used for balancing the model)..

---------------------------------------

PIN CONFIGURATION:

1// HC-05..

the bluetooth module consists of 4pins namel:

# tx- transmitting pin..(must be connected to the rx pin of arduino )

# rx- receving pin...(must be connected to the tx pin of the arduino)

# vcc- power supply 5v

# gnd- ground pin (must be connected to the gnd pin ......above pin 13 of arduino)

------

2// l293d motor driver:

# 16 pin are present in this chip..

# pin numbers

/// 4,5,12,13 ==> gnd pin

/// 1,8,9,16 ==> +12v supply

/// 2,7,10,15 ==> pins connected to arduino

/// 3,6 ==> left motor

3 ==> -ve wire

6==> +ve wire

/// 11,14==> right motor

11 ==> +ve wire

14 ==> -ve wire

-----------------

ARDUINO PINS:

# vin ==> power supply vout of 7805 regulator..

# gnd ==> to the ground of 7805 regulator

# gnd (above the d13 pin) ==> to gnd of 7805

d9 ==> to pin 15 of l293d

d10 ==>to pin 10 of l293d

d11 ==>to pin 7 of l293d

d12 ==>to pin 2 of l293d

#DIAGRAM DESCRIPTION:

red wire : +ve supply

black wire : gnd

purple,yellow,green,orange == arduino wires to l293d.

------------------------------------------------------------------------------------

MAKING OF THE MODEL

a wooden board 0f length 50 cm

width 20 cm;

make the centre point for the length and width..

place the motors using the clamp at either sides underneath the board

ensure the motor perfectly fits to the clamp else the motor would struck..

place the rolling wheels at the four corners ..

BLUETOOTH APP CONTROLLER:

download the app from playstore

# set the keys as per the numbers provided for the path..

the complete circuit can be made in a single breadboard...for convenience i made it by 2..

THANK U...

HOPE U LOVE IT..
