Blynk
Welcome to the Blynk community! Join to share projects and receive help.
Blynk is a toolset for all makers, badass inventors, designers, teachers, nerds and geeks who would love to use their smartphones to control electronics like Arduino, RaspberryPi and similar ones. We’ve done all the hard work of establishing internet connection, building an app and writing hardware code.
All for you. 
 
With Blynk, you simply snap together an amazing interface from various widgets we provide, upload the example code to your hardware and enjoy seeing first results in under 5 minutes! It works perfectly for newbie makers and saves tons of time for evil geniuses.
 
Blynk will work with all popular boards and shields. We wanted to give you full freedom when deciding how to plug Blynk into your existing or new project.
 
You will also enjoy the convenience of Blynk Cloud. Which is, by the way is free and open-source. You can even run it locally on your Raspberry Pi.
