Lab 5: Choose your Own Adventure

We are trying to create a toy car that can do the following

git clone git@github.com:cmu14642/f22-lab5-nerds.git
git checkout peripherals
sudo picocom -c --imap lfcrlf /dev/ttyBmpCon
cd f22-lab5-nerds
make run

User can interact with the car interface using picocom terminal and provide inputs as shown in the instructions

The services are running in 4 threads that implement the following functions

user_input() : This thread is always running and looking for user input and performs state management. The method assumes that user is done giving input when enter is pressed. Once user presses enter this thread will perform application state management and update the global variable user_in[] to ensure the updated state/input is shared with all the threads.
move_car() : If user provides inputs like 'forward', 'backward', 'left' or 'right', this thread will automatically unblock and execute the requested operation. The connected DC motor will perform the rotation accordingly.
glow_onboard_leds() : When user gives input like 'glow' the on board LEDs will start blinking. These are our parking lights.
neo_dance() : When user gives input like 'dance' a dance party will be started. This means neo pixel will flash different colors based on the frequency of music being played.

Other features:

If user gives input like 'pause' the currently running operation will stop and the car will just wait for new instructions.
If user gives input like 'exit' the car will free up all its resources, clean up its threads and stop.
