USB Sensor Setup
Your Arduino talks to this app over USB. Most boards work as soon as
they are plugged in. Boards built around the
CH340 chip, which is most inexpensive
Nano and Uno clones, need a small driver installed first on Windows.
The download opens on the chip maker's own site. This app cannot
install it for you: browsers are not permitted to install system
drivers, and that restriction is what keeps a web page from
changing your machine.
Step 2 — confirm the board is seen
Plug the board in, then press Check. Your browser will ask which
device to allow: pick the board and choose Connect.
