In context with my published project on the 7 segment display, I have left me two challenges unanswered, to which I know no answer:
My primary question is, can I switch on/off the LED display (I need it at night only for a few seconds via a PIR motion sensor or touch sensor to activate the display; otherwise it will be permanently switched off.)?
My second question is, how can I manipulate the display to also outputs the representation of a leading 0 during hour 0 (0:03 instead of x:x3)?
// Get the current time in HHMM format the_time = Time.hour()*100+Time.minute(); //Serial.println(the_time);
