i have been using this particular code for about 1/2 year
nowtrying to update i receive this error code

Arduino: 1.8.5 (Windows 10), Board: "Arduino Pro or Pro Mini, ATmega328P (5V, 16 MHz)"

option enabled in File -> Preferences.

not sure what to do now

i should i deleted ide and reinstalled a fresh copy

aug_16_1307_hot_water_timer.ino (7.82 KB)

Upload the working code the one before your "update".

Undefined reference to main? And it's not finding the write method of print?

Does anything else compile? Try like, compiling blink... It looks like builder is misbehaving; have you exited and restarted the IDE since this started? Sometimes weirdo problems like this are caused by the cache getting messed up.

So I pasted the current blink code to a new file, tried to compile and

error message as follows :

collect2.exe: error: ld returned 1 exit status

exit status 1

This report would have more information with

when I get down the list to the /bin/.. etc on my sreen there a list of files but differentthan I have been used to viewing, not sure where after the bin file to go as it is listed as ..

thanks for your time

this is the blink verbose info from above file

Near the end it says it is linking it all together is where the error starts and printing turns orange

Close ALL Arduino IDE windows. Then restart the IDE and try compiling again.
