Assignment $\backslash$#$4-$ Reaction Time Game

In this assignment you will use the InterruptIn, Timer, Serial, and DigitalOut interfaces on the mbed module to implement a $2$ player reaction time game. $($Depending on how you choose to implement this, you may also want to use Ticker and$/$or Timeout as well$)$ For the hardware, connect one of the pushbutton switches $($for player $1)$ between p$14$ and GND and a second switch $($for player $2)$ between p$21$ and VOUT.

Each round of the game starts will all of the LEDs off. Then LED$4$ turns on$,$ then LED$3,$ then LED$2,$ and finally LED$1$ for $1$ second each. The objective for each player is to press their switch as soon as possible after LED$1$ turns on$,$ but not before. If a player pressed their switch before LED$1$ turns on$,$ they forfeit the round and the other player gains a point. Otherwise, whichever player presses their switch first after LED$1$ turns on gains a point.

At the end of each round, show $($via Serial over the USB interface to your computer$)$ the deciding time $($in milliseconds$)$ as well as the current score. For example $($with x filled in with the appropriate number$)$:

$```$

Player x was xxxx ms too early and lost.

Player $1$: xx points, Player $2$: xx points

$```$

or

Player x won with a reaction time of only xxxx ms$.$

Player $1$: xx points, Player $2$: xx points

Then the program should pause for a few seconds $($to give the players a small rest and let them release their switch$)$ and start are new round.

As is usual for most games, both players should start with $0$ points. For simplicity, you don't have to worry about the end of the game; the players can decided to stop playing whenever they want and if they want to reset the total score, they can just reset the mbed.

The serial interface should use $9600$ bits$/$second $("$baud$"),8$ bits, no parity, and $1$ stop bit $($this is the default$).$

Submit your "main.cpp$"$ to the appropriate dropbox on Canvas by the end of October $23.$
