I understand from the instructions below that you can enable debugging - will this also work for a serial connected Arduino UNO? where can I find/follow that log?
Thx, Gernot
To enable debug prints on the default Serial, add on the top of your sketch (should be the first line ):
#define BLYNK_DEBUG // Optional, this enables lots of prints
#define BLYNK_PRINT Serial
And enable serial in setup():
Serial.begin(9600);
