- Download latest Blynk library here:
- https://github.com/blynkkk/blynk-library/releases/latest
- Blynk is a platform with iOS and Android apps to control
- Arduino, Raspberry Pi and the likes over the Internet.
- You can easily build graphic interfaces for all your
- projects by simply dragging and dropping widgets.
- Downloads, docs, tutorials: http://www.blynk.cc
- Sketch generator: http://examples.blynk.cc
- Blynk community: http://community.blynk.cc
- Follow us: http://www.fb.com/blynkapp
- http://twitter.com/blynk_app
- Blynk library is licensed under MIT license
- This example code is in public domain.
- *************************************************************
- This example shows how value can be pushed from Arduino to
- the Blynk App.
- WARNING :
- For this example you'll need Adafruit DHT sensor libraries:
- https://github.com/adafruit/Adafruit_Sensor
- https://github.com/adafruit/DHT-sensor-library
- App project setup:
- Value Display widget attached to V5
- Value Display widget attached to V6
