- All right, now for a brief demo.
On my left is the legitimate polling system.
And as always, if I select an answer on my remote,
it'll be broadcast and received by the base station.
On my right is an Arduino running the custom firmware
and initialized to a random serial number.
It's connected to my laptop right now with a USB
so I can manually send it commands.
And if I instruct it to broadcast an answer
as if it were a remote,
right now, it'll look to the base station
as though another student is submitting an answer
using their remote.
Now, let's try this again,
but this time I'm going to set the Arduino
to the same serial number as my remote.
Now, if I click in with the remote as normal
and then instruct the Arduino to broadcast an answer,
it appears to the base station as though the same student
is simply changing their response.
In effect, these two devices
are acting as if they are the same remote.
