Project Overview & Quickstart (Blynk-Technologies/blynk-library) # Blynk C++ Library [](https://github.com/Blynk-Technologies/blynk-library/releases/latest) [](https://github.com/Blynk-Technologies/blynk-library/releases/latest) [](https://github.com/Blynk-Technologies/blynk-library/issues) [](https://github.com/Blynk-Technologies/blynk-library/blob/master/LICENSE) If you like **Blynk** - give it a star, or fork it and contribute! - [](https://github.com/Blynk-Technologies/blynk-library/stargazers) - [](https://github.com/Blynk-Technologies/blynk-library/network) __________ [](https://vshymanskyy.github.io/StandWithUkraine) #### Blynk is a unique IoT platform for connecting any hardware to the cloud, designing apps to control them, and managing your deployed products at scale. - With Blynk Library you can connect **over 400 hardware models** (including ESP8266, ESP32, NodeMCU, all Arduinos, Raspberry Pi, Particle, Texas Instruments, etc.) to the Blynk Cloud. - With Blynk apps for **iOS** and **Android** apps you can easily drag-n-drop graphic interfaces for any DIY or commercial project. It's a pure WYSIWG experience: no coding on iOS or Android required. - Hardware can connect to Blynk Cloud over the Internet using hardware connectivity available on your board (like ESP32), or with the use of various shields (Ethernet, WiFi, GSM, LTE, etc). Blynk Cloud is available for every user of Blynk **for free**. ## Downloads **Blynk [Arduino Library](https://github.com/Blynk-Technologies/blynk-library/releases/latest)** **Blynk Mobile App: [ Google Play](https://play.google.com/store/apps/details?id=cloud.blynk) | [ App Store](https://apps.apple.com/us/app/blynk-iot/id1559317868)** ## Quickstart: Arduino + Ethernet shield * Download the Blynk app ([App Store](https://apps.apple.com/us/app/blynk-iot/id1559317868), [Google Play](https://play.google.com/store/apps/details?id=cloud.blynk)) * Get the Auth Token from the app * Import this library to Arduino IDE. Guide [here](http://arduino.cc/en/guide/libraries) * In Arduino IDE, select `File -> Examples -> Blynk -> Boards_Ethernet -> Arduino_Ethernet` * Update Auth Token in the sketch and upload it to Arduino * Connect your Arduino with Ethernet shield to the internet When you are connected - check the included examples on how to use different types of connections (transports) and explore Blynk features. You can combine any example for your hardware + transport + features. ## Documentation and other helpful links [The list of supported hardware](https://docs.blynk.io/en/blynk.edgent-firmware-api/supported-boards) - supported boards, Ethernet, WiFi, Cellular...
