Compiling Error Due to Exit Status 1 - Digital Pin related...

Projects Programming

I have a very strange compiling error which is driving me crazy trying to work out what is going on. Hopefully someone on here can point out what might be happening..

I am in the middle of creating an Arduino project which involves activating relays and readings analogue values for testing reasons.

I am trying out a small section of code in a separate file just to get some readings.

when I try and compile it I get this error message:

collect2.exe: error: ld returned 1 exit status

exit status 1
Error compiling for board Arduino/Genuino Mega or Mega 2560.

I have attached the code.

I have narrowed the problem down to the final line of code "digitalWrite(K3,LOW);"

If I remove this it compiles fine. So it is like it is not allowing me to make the pin LOW which is bizarre since this should not be a problem and have never had this problem before...

Any ideas?

Thank you in advance.

Please post your code, and the full error message.

Compiles fine for me - Mac and version 1.6.12 of the IDE.

I just downloaded the file that I attached and now it compiles fine...

I have no idea what made the difference but I have saved it and all good again.

Thank you
