Noticed a few bugs:
- Pressing ctrl-C didn't stop the program right away since it only
checked for interrupts after completing the loop
- The LEDs start off, so turning them off at startup isn't strictly
necessary
- .gitignore wasn't ignoring all the right stuff, switched to
gitignore.io
Ended out unrolling this into a state machine, mostly just to practice
some rust.
Example run, with debugging enabled:
pi@raspberrypi:~/rust/rustpitrafficlights $ RUST_LOG=debug cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.10s
