This board has dual motor driver & some extra Arduino pins, 3V,5V,GND out so Using this PCB you can make line follower, obstacle avoider, edge finder, voice control & other Arduino robots by changing Arduino code.
I have made a bluetooth control robot car so I am describing how to make Bluetooth control Arduino robot or car
Upload the code to Arduino nano
Download Arduino code for Bluetooth control robot car & more details - from here
open the downloaded code with Arduino IDE software & upload it to your Arduino nano.
Download Bluetooth RC controller from play store
I am using Arduino Bluetooth car controller app Bluetooth RC controller
from play store but
you can use any Bluetooth controller app but need some changes in Arduino code.
