bluetooth car using arduino & L293D chip

Hey there!, In this post i will show you how to make bluetooth car using arduino and L293D chip

let's begin with requirement of hardware.

Component required:

• Arduino UNO

• L293D IC Or H-Bridge

• HC-05 Bluetooth Module

• BreadBoard

• Chassis

• 2xDC Motors

• 9V Battery Or Power Bank

• Jumper Wires

Getting the chassis ready:

You Can Buy A Readymade One.

For Making A Chassis:

• Find A Rectangular Wooden or Plastic Plate.

• Attach The Motors to It With the Help Of Glue Gun Or Double Sided Tapes.

Wire Up The Circuit According To the schematics.

(note: here I have used 4 battery)

Summing up the circuit

Just Follow One By One Wire And You Will Do It Perfectly

Note:

• If The Motors Behave in Opposite Direction,Just Reverse The Polarity.

• If You Are Using 5V Motors,Then You Can Connect the Pin 8 Of the L293D To 5V Of Arduino.

Uploading the code:

here, link a of arduino code , you can download.

upload the code to arduino.

Note: Remember To Disconnect The VCC Pin Of HC-05 Before Uploading Code
