but no sketch running.
In your picture of the setup, it looks like the humidity sensor power is connected backwards.
If the upload was successful then the sketch will be runningPut some Serial.print()s in the code at strategic points such as entry to and return from functions and print out the value of pertinent variables. Is the code calling the functions that you expect and are the values of variables sensible ?
But it didn't work
Did you add a Serial.begin() to setup() ?
I've just added Serial.begin() now in the void setup(void) section, but the sketch won't compile.
What baud rate did you specify in the the begin() function ?
It was 57600 as specified in the said sketch
Which sketch is that ?What error did you get ?
