Make a laptop controlled robot. via instructables

It would be so good if would be able to control a robot or your rc car using a laptop just like you control a car in a game. Well, it can be made possible using the versatile arduino UNO. There are thousands of projects you can make with arduino. This one of those projects. It is basically a robot which can be controlled over a laptop or pc. It can be connected to your pc using bluetooth. It uses an HC-05 bluetooth module which is connected to arduino UNO. When you press a button on the keyboard, a string of data is sent to bluetooth module through the bluetooth of laptop. The module then transmitts the data to arduino which processes it. Arduino then sends a signal to motor driver ic which conducts current to the motors and the motor spins.

For making this robot you would need the parts and tools listed below. Most of them can be bought from ebay or radioshack.

PARTS-:

1x Arduino board (UNO)

1x HC-05 Bluetooth module

1x 12v Battery (according to your requirement,i’m using 1.3AH)

4x DC Geared motors (speed and torque according to your requirement)

4x Wheels for motors (i used two small ones and two big ones)

1x Adapter Jack (to power the arduino board)

1x L293d motor driver ic

8x Male jumper wires

1x Breadboard

Rainbow cable (for motor connections)

Jumper cable (for breadboard connections)

Alligator clips (for connecting battery)

LEDs- 2x red, 2x white (if you want to add front and rear lights)

Male headers

TOOLS-:

-Soldering Iron
-Soldering Wire
-Fume Extractor (if you don’t like the bad smell of burning flux)
-Wire Cutter/Stripper -Double Sided Sticky Foam Tape
