The setup of the fire alarm project
The program
The program must combine several levels. The ThingSpeak-page is very import-
ant again. Among others, the threshold monitoring of the NTC is assumed by a
ThingSpeak-app. From there, the alarm action is performed, i.e. sending a Twitter
message and inserting a TalkBack-command that trips the alarm on the controller.
In the first step, you need to set a new channel on the ThingSpeak-page. You can
name it FireAlarm, for example. The field 1 is then given designation Temp. Under
API Key, you will find the first key that you need to enter for ThingSpeakKEY. This
ensures transmission of the current temperature.
As a second step, you should generate a new TalkBack element. You can name it,
e.g. Alarms. You can also have the commands logged in the channel FireAlarm. You
need to enter the API key after TalkBackKEY and the ID after TalkBackID. Now you
can also send commands to the board. You can also enter commands manually by
clicking the Add a new Command in the TalkBack overview of the Alarm channel
and then enter it under Command String Alarm. You do not need to enter the posi-
tion, since the command is automatically saved in the first location. You can now
upload the program and test whether the transfer of the current temperature value
works and whether the board executes the commands. In this place, it will also help
to calibrate the NTC via the potentiometer with a room thermometer.
