Switch

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. ...

In yesterday’s program, the first commands were evaluated by the controller. Today’s program maintains this function but can also additionally send a command into the network independently. The button on pin D8 You will find a button behind today’s door. It is used as a simple sensor here. Connect it to the controller as shown in the setup image. The program: Day6_UDPSwitch ! Attention: Some MAC-Users reportet a bug in the PacketSender-Software. This bug doesn’t allow you to change the ports. If you have problems with this bug you can change the ports in the Arduino program. All you have to do for todays project is to change the line 83 from succes &= sendCom(“AT+CIPSTART="UDP","192.168.4.255",90,91”, “OK”); to succes &= sendCom(“AT+CIPSTART="UDP","192.168.4.255",5505,5506”, “OK”); ...
