App Description

Control Arduino, Raspberry Pi, ESP8266, ESP32, Particle Photon and Electron, and many other microcomputers with an iPhone?

Building a smart home or robot? Just learning electronics? - Blynk works for everyone.

Blynk is the first and only drag-n-drop mobile app builder for the microcontrollers and Internet of Things (IoT)

Connect any sensors and control any actuators connected to your board.

Use a wide variety of widgets like buttons, sliders, graphs etc. to visualize sensor data and control any electronics from anywhere in the world with your own app.

Blynk is easy. You will start tinkering in 5 minutes!

All you need:
1. Set up widgets with a just a few clicks
2. Upload Blynk example sketch code to your hardware
3. Enjoy Blynking!

Check the examples in the library to get started and build Your Internet of Things. It doesn't matter if you are newbie or pro.

Blynk works with every hardware you can imagine, even with Bluetooth Low Energy(BLE)
