Intro: SIMPLE CARBOT || ARDUINO || BLUETOOTH CONTROL || TUTORIAL

IN THIS INSTRUCTABLE I WILL SHOW HOW TO MAKE A SIMPLE BOT THAT IS CONTROLLED BY YOUR SMARTPHONE VIA BLUETOOTH

PARTS NEEDED:

☻ARDUINO

☻2X GEAR MOTORS

☻HC-05 BLUETOOTH MODULE

☻LAPTOP OR PC (FOR UPLOADING CODE TO ARDUINO

☻POWER SUPPLY ( I USED A POWER BANK TO SAVE BATTERIES)

☻JUMPER WIRES

☻WHEELS

☻CHASSIS (CAR BODY)

STEP 1: PREPARE THE WHEELS

I JOINED TWO WHEELS TOGETHER TO MAKE A WIDE WHEEL AS SHOWN IN ORDER TO GAIN MORE STABILITY

FOR EXTRA STABILITY I USED SUPER GLUE AND REMOVED EXTRA GLUE USING ACETONE

STEP 2: FIX THE MOTORS TO THE CHASSIS(CAR BODY)

FIRST SOLDER TWO JUMPER WIRES TO EACH OF THE MOTORS AS SHOWN

NEXT, FIX THE MOTORS TO THE CHASSIS USING BOLT .

STEP 3: ATTACH THE WHEELS TO THE MOTORS

PRESS AND TWIST A LITTLE TO ATTACH TO THE WHEELS TO THE MOTOR

STEP 4: WIRE UP THE MOTORS TO THE MOTOR DRIVER

JOIN THE 4 WIRES FROM THE MOTOR TO EACH OF THE 4 OUTPUT OF THE MOTOR DRIVER.

STEP 5: CONNECT MOTOR DRIVER TO ARDUINO

CONNECT EACH OF THE 4 INPUT OF THE MOTOR DRIVER TO PIN 8,9,10,11 RESPECTIVELY OF TH E ARDUINO UNO

STEP 6: POWER SUPPLY FOR MOTORS

I USED A USB TO SUPPLY POWER TO MY BOT

SIMPLY STRIP OF THE FREE END OF THE USB AND REMOVE THE INSULATION TO REVEAL 4 WIRES.

KEEP BLACK AND RED WIRES AND CUT OF THE OTHER TWO WIRES.

JOIN RED TO + AND BLACK TO NEGATIVE OF THE MOTOR DRIVER POWER SUPPLY.

STEP 7: CONNECT BLUETOOTH

CONNECT THE BLUETOOTH DEVICE HC-05 TO THE ARDUINO:

connect rx of bluetooth to tx of arduino

connect tx of bluetooth to rx of arduino

vcc to +5v

gnd to gnd

STEP 8: UPLOAD THE CODE

OPEN THE CODE WITH THE BELOW LINK AND UPLOAD TO THE ARDUINO

LINK:https://drive.google.com/open?id=1LFiq5kcdtwzrAfNUjZtbnxqNwQx4e9pM

NOTE: REMOVE THE TX AND R PIN OF BLUETOOTH BEFORE UPLOADING THE CODE

STEP 9: BLUETOOTH APP

☻Download Arduino Bluetooth controller from play store

☻click on connect and select yourbluetooth device.

☻open the controller mode and click on set commands from the side menu

☻Set the values as

up-1

down-2

left-3

right-4

NOTE: YOU MAY NEED TO DO A LITTLE TRIAL AND ERROR AND CHANGE THE CONFIGURATION OF THE CODE OR MOTORS A LITTLE IN ORDER TO GET THE DESIRED OUTCOME

STEP 10: CONGRATS!!

YOU JUST FINISHED MAKING THE BOT

NOW YOU CAN CONTROL THE BOT FROM YOUR PHONE.

NOTE: YOU CAN ALSO USE 9V BATTERIES TO SUPPLY POWER TO MOTOR DRIVER AND AVOID USING A POWER BANK
