Make sure that the serial port isnt blocked by another application, such as
a serial monitor window you forgot to close.
Exercises
Build an automatic burglar alarm that shows a stop sign whenever
someone is too close to your computer.
4
Make the application as smart
as possible. It should have a small activation delay to prevent it from
showing a stop sign immediately when its started.
The speed of sound depends not only on the temperature, but also on
humidity and atmospheric pressure. Do some research to find the right
formula and the right sensors. Use your research results to make the
circuit for measuring distances even more precise.
Use an alternative technology for measuring distancesfor example, an
infrared sensor. Try to find an appropriate sensor, read its data sheet,
and build a basic circuit so you can print the distance to the nearest
object to the serial port.
