SW getting started Blynk LEGACY

Blynk IOT requires TEMPLATE_ID to be defined at compilation time, for this reason, there's no pre-build firmware for it.

Download/Clone this project, then, using Arduino IDE or VSC(Platformio) check the file named config.h.

Make sure #define USE_BLYNK is enabled/un-commented
Make sure #define USE_BLYNK_2 is enabled/un-commented
Make sure #define USE_MQTT is disabled/commented
Insert your BLYNK_TEMPLATE_ID blynk docs
Insert your BLYNK_DEVICE_NAME
Insert your BLYNK_AUTH blynk docs

Compile the sketch and upload to your ESP module.
