Arduino Duemilanove

You have to select UNO in the Blynk App board type, not the DUE (which refers to the Arduino Due).

ESP8266

Generic ESP8266, NodeMCU, Huzzah, WeMos D1, Seeed Wio Link, etc.

ESP8266-based boards can run Blynk directly on the ESP8266 chip, using this board support package: https://github.com/esp8266/Arduino

Tutorials:

• Getting started with Blynk: https://learn.sparkfun.com/tutorials/esp8266-thing-development-board-hookup-guide/example-sketch-blink-with-blynk
• Getting started with ESP8266: http://www.esp8266.com/wiki/doku.php?id=getting-started-with-the-esp8266

Pitfalls:

• ESP8266 can't be powered from 3v3 pin on most Arduino, as it requires >400 mA current.
• ESP8266 flash might get broken. The code executes without problem right after flashing, but stops working after first reboot.
• This WiFi module can somehow interfere with PIR sensors -> PIR sensor starts producing random values ;)

Particle Electron

NOTE: Blynk can consume quite a lot of data! Use carefully not no overpay for the data plan.
