Terminal Blynk to bardzo użyteczny Blynk Widget. Zwłaszcza wtedy, gdy nie możemy korzystać z monitora szeregowego Arduino IDE. Na przykład wtedy, gdy programujemy urządzenia przez WiFi używając procedur OTA.

Funkcje
- WidgetTerminal terminal(V1);
- terminal.clear();
- terminal.write(param.getBuffer(), param.getLength());
- terminal.println(F(„Blynk v” BLYNK_VERSION „: Device started”));
