====== HW 02 - First program on embedded platform ======

The result of this homework is a file with code (main.c - file name is important) for the **embedded platform** (not for PC) which allows communication between the board and the computer. Please **do not upload the whole project**.

You will write code for **a single program** that will listen for user commands, and then act on these commands, which builds upon lab 4.
HINT: It might be useful to make use of the timeout (variable set to 360000 in the lab code).

  * The user can send a command to turn the LED On
  * The user can send a command to turn the LED off
  * the user can send a command to toggle the led on/off
  * The user can send a command to make the LED blink until the user sends a new command
  * EXTRA: The user can send a command that will make the LED blink like above, but slowly get faster
  * EXTRA: The user can send a command that will make the LED blink like above, but slowly get slower
  * EXTRA: When the user sends an unrecognised command, the board will reply with a list of possible commands
  * The source code should be commented, including a list of possible commands and what they do
