Sending Temperature to Blynk¶ This example is an demonstrations of sending data from Wio Terminal to the Blynk server of which can then be viewed on the mobile app. Blynk grants access and shows the empty dashboard previously created with the client. Hopefully they will include Industruino boards in new Blynk realeases so there will be no need to do this modifications anymore. On the Blynk application, I've defined 6 virtual pins and one digital output pin, listed below: V0 temperature from BMP180, read V1 pressure from BMP180, read V2 temperature from DHT, read V3 humidity from DHT, read V4 alarm LED, read V5 reset from remote, write; D23 A/C relay. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Broker for Internet monitoring and control tests, are available to connect from any MQTT client in this case we will use HIVEMQ, which has. com and password, and press the Log In button. If you are using Arduino then you should be quite familiar with Serial monitor which is used for reading the strings and sensors data. It means that Blynk app will request the data from Virtual Pin V5 every 3 seconds (when app is open, of course). """ [READ VIRTUAL PIN EXAMPLE] ===== Environment prepare: In your Blynk App project: - add "Value Display" widget, - bind it to Virtual Pin V11, - set values range 0-255 - set the read frequency to 5 second. Now we use the virtual pins. V1, which we're using in this example to control the Blynk LED state, is one of the Blynk project's 32 virtual pins - a custom-programmed input or output, that can read or write values of all types to the Blynk Board or app. AnalogIn(board.
