Morse Code through CPU utilization.
Usage
The API exposes two simple functions, dit and dah. dit will utilize the
CPU for a second, dah will sleep. Knowing this, we can exchange information
by looking at the program’s CPU utilization every second. A simple POC is
included in main.c and observe.sh. It’s really, really crude. For best
results, compile without optimizations.
Have fun!
