Today’s project is about another app of the ThingSpeak page, i.e. the TalkBack-App. This function permits creating a command that is read and executed by the controller. What appears nonsensical with a single controller does make sense when using two or an entire network of controllers. Some boards can act as sensors then, e.g. with motion detectors, and send a TalkBack command. Another module reads the command from the ThingSpeak page and then opens the door or reports an alarm.<\/p>\n

\"Aufbau<\/a>

Two Buttons on D5 and D10 and a LED on D9<\/p><\/div>\n

You will find another button behind today’s door. The setup of today’s experiment consists of an LED with a dropping resistor and two buttons as the figure shows.<\/p>\n

The program:\u00a0Day22_ThinkSpeakTalkback<\/a><\/strong><\/p>\n

First, you need to create a new TalkBack channel under APPS \u2013 TalkBack. If you like, you can also have the commands entered in a channel. This can be the already-created light channel of the 19th day, or a dedicated channel. All commands are then logged. Particularly the API key, which you will enter in #define TalkBackKEY, is important. In addition to the API-KEY, you now also need an ID, which you will find in the overview under TalkBackID, after you have clicked Save-TalkBack. Enter #define TalkBackID into the program here.<\/p>\n

\"Die<\/a>

The TalkBack-APP<\/p><\/div>\n

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.<\/p>","protected":false},"excerpt":{"rendered":"
