BLUETOOTH CONTROLLED ROBOT

The project uses an arduino which is connected to a bluetooth module whichproduces a wireless connectivity between a laptop and the arduino. So when

we press a button on our laptop, data is passed on to the Robot through

bluetooth enabled in the laptop and received through the bluetooth module

present in the robot. The data is then transmitted to arduino which is

programmed in such a way to accept the data, process it and perform a tasks

mentioned as per control of data mentioned below.

For e.g. if we press a button that moves the robot forward, the arduino

receives the command through bluetooth and sets two of the pins high as it

is programmed to do so. The signal is then transmitted to the motor driver IC

which drives both the motors and the robot moves forward.
