Internet of Things Using Tiva LaunchPad

%% This code sends commands to the ESP8642 module configured as WiFi Server 
% The module is interfaced with the TivaC Launchpad which is attached to 
% the two sensor modules Viz:- the stepper motor and the servo motor
% Both the motors are controlled through the commands received by the ESP
% module and serviced by the TivaC Launchpad configured as the master controller
