general Kenob... ok sry.
I want to trigger the rtc. Or the Internal Clock of the Arduino Uno.
After a HIGH or true the clock should count the seconds, minutes and hours till the clock gets a LOW. After the low the clock have to reset.
I found this arduino-projects/simple_clock.ino at master · onetransistor/arduino-projects · GitHub and i like it. How could i trigger the clock. Reset it to 00:00:00 and let ir count again at a HIGH.
