Blynk was designed for the Internet of Things. It can control hardware remotely, it can display sensor data, it can store data, visualize it and do many other cool things.
There are three major components in the platform:
- Blynk App – allows to you create amazing interfaces for your projects using various widgets we provide.
- Blynk Server – responsible for all the communications between the smartphone and hardware. In our project, you need to install a private Blynk server in your PC(Windows,macOS, Raspberry Pi etc)locally. It’s open-source, could easily handle thousands of devices and can even be launched on a Raspberry Pi.
- Blynk Libraries – for all the popular hardware platforms – enable communication with the server and process all the incoming and outcoming commands.
Now imagine: every time you press a Button in the Blynk Legacy app, the message travels to the Blynk server , where it magically finds its way to your hardware. It works the same in the opposite direction and everything happens in a blynk of an eye.
Do I need to develop an Cell phone APP to customize my IoT applications?
No! With Blynk Server and Blynk legacy APP, you no need to know how to program your Android or iOS APP, just drag and drop widgets and you can make your cell phone become the controller of remote and enjoy the beauty of Internet of Things.
Do I need to pay for Blynk services?
If you are using Blynk legacy APP and local Blynk Server, the whole service is absolutely free. However, Blynk cloud has developed new Blynk IoT APP and server which have more advanced easy to use features. If you want to use new Blynk Cloud service, you might need to pay Blynk company subscribe fees ?
