The easiest way to extract the sound from a video is to use our audio converter.
Open the audio converter.
Click "Open files".
In the resulting window select the file you wish to extract the sound from. ...
While the sound is being extracted, choose the format in which you want to convert the sound.

Installing the silabs Silicon Labs VCP Driver.pkg worked for me also. 👍
(on OS X 10.11.6)

Seems obvious that we need the drivers, but I thought I already had them after going thru the espressif/arduino-esp32 install steps.
e.g. My "System Report / Hardware / USB" showed
CP2102 USB to UART Bridge Controller driver

For others' future reference, you should see something like:
n8s-iMac:nleon$ ls -al /dev/tty.*
crw-rw-rw- 1 root wheel 18, 2 Jul 4 11:14 /dev/tty.SLAB_USBtoUART

Regardless, thanks for the pointer!

Most people simply called it a serial connection. At one time, it was the most used form of data transmission. You will probably recognize the standard 9 pin DB9 cable. Simply put, a RS232 connection transmits signals using a positive voltage for a binary 0 and a negative voltage for a binary 1.

M5ez is an Arduino library. To start using it with the Arduino IDE:

Choose Sketch -> Include Library -> Manage Libraries...
Type M5ez into the search box.
Click the row to select the library.
Click the Install button to install the library.
Repeat this process for the ezTime library
in File -> Examples you will now see an M5ez heading down under "Examples from custom libraries"

You'll have your first application on the screen in no time. You can also start with one of the sketches below in the "Menus" section of the documentation. In fact we strongly recommend that you play around with the M5ez demo application, since it is a comprehensive showcase of M5ez's functionality that will give you a good feel for what you can and cannot do with M5ez.

OTA stands for Over the Air (FOTA – Firmware Over the Air). It refers to the wireless delivery of new or updated software or firmware to devices such as smartphones and tablets.

The DS18B20 uses Maxim's exclusive 1-Wire bus protocol that implements bus communication using one control signal. The control line requires a weak pullup resistor since all devices are linked to the bus via a 3-state or open-drain port (the DQ pin in the case of the DS18B20).
