Setup with two switches at D5 and D10 and an LED at D9
The program
First, you need to create a new TalkBack channel under Apps/TalkBack. You can
use, e.g., Doors as the name. If you like, you can also have the commands en-
tered in a channel. This can be the already-created light channel from the first
ThingSpeak-
experiment, or a dedicated channel. All commands are then logged. Particularly
the API key, which you will enter in #define TalkBackKEY. In addition to the API-
KEY, you now also need an ID, which you will find in the overview under TalkBack
ID TalkBackID, after you have clicked Save TalkBack. Enter this ID behind #define
TalkBackID in the program.
If you upload the program now and call the serial monitor, you will first see the
message No Command. Push one of the two buttons now. After a brief time, the
message OpenDoor or CloseDoor, will appear, depending on which button you
pushed. For the OpenDoor-command, the LED will also light up.
