Hi.
I have a problem compiling my code, can’t find out what the problem is.
I have reinstalled the program and all the lib´s and updated but still the same problem.
The coding is running smoothly without the Blynk, but when I insert the Blynk coding, my servo stop working and the ultrasonic sensor measurement freeze on the LCD.
I also cannot change the blynk-ser to port 3, instead going to port 1
Here is the error code, can anybody help ?
