SMARTPHONE CONTROLLED BLUETOOTH CAR

hello friend so today we all will be makinga smartphone controlled bluetooth roobot

and guys dont forget to follow my instagram page

www.instagram.com/build_more/

gather the parts from your locals

robot chasis

4 dc motor (200 RPM)

bluetooh module (HC-05)

arduino uno

4 wheels as per the motor shaft

motor driver module LM293D

smartphone

12 v 1 amp battery

downlaod the bluetooth car app named(BLUETOOTH RC CAR) on google play in your smart phone

remember remove the rx tx pins of bluetooth while uploading the code otherwise it may generate an error.

this is the motor connection that how it is to be done and mind well that the polarity on the other side of the wheels is reversed because it spins oppositely

grab your arduino software

and download the given file and upload the code into the arduino baord by connecting it to your pc or lapotp

the 2 3 4 5 pins of arduino are to be connected on to the motor driver there will be issues of polarity change so guys first try 2 3 on m1 and 3 5 on m2 then if not working then reverse the polarity but make sure not keep 2 and 4 pin together as they are the plus pins for out to motor driver,

and remember guys for the bluetooth module the rx tx and arduino rx tx will be cross conected

as the input for the bluetooth and generate output and give to arduino so that output of bluetooth is iput to arduino

and dont forget to give the supply to the arduino through powerbank

if you guys have any issues any doubts then please contact me on
