I am using a micro data logger with RTC on a Arduino Mega 2560.
I have snipped two programs, one for the RTC and one for the data logger.
I give a high input to Pin 7 when I want to log the v (actually mv) and percent.
I am trying to log mv and percent where percent equals mv times a scale factor.
The data logger logs the date and time, but only logs 0 0 for mv and percent.
The Serial monitor displays the mv and percent, but shows 0 0 for the data logger.
Please see attached sketch and pictures of the Serial monitor.
Please help me as I have tried with any hours of research. I think it has to do with logging the float, but can’t find a fix. Thank you for your help.
