I know that I can start a timer when an output goes on/high but can't work out the logic to detect when it goes off/low, stop the timer and then write an entry to the SD card with the time elapsed before resetting that time ready for the next time the output goes high. It will not do this very often, so no issues with trying to write too often. Your help would be most appreciated. Thank you

But just know: The saved value is the total value of the time base of the stopwatch. Example: Is the time base seconds an the output is 2 minutes and 41 seconds high, then would a value of 161 (seconds) saved in the Data Log. Attachment Stopwatch_0BA8.Standard.zip (52 Downloads)
