In README.md
in the example code for the buzzer playing notes from a table
pwm.setPwmFrequencyHz(frequencies[i]);
should be

Hello guys,

Thank you for this nice workshop. It's really helpful.
I started to play around with AndroidThings myself.
Here is a little project I did. Any comment is more than welcome.

I would like to know more about the close() method we should call on any device used.
What does it do exactly ?
What is the right pattern related to this ? Should we close it as quick as possible ? Or should we let the device "open" if we know that we will eventually update it ?
What happens if we don't close() it ?

Thanks \o/
