RTC Alarm using serial monitor
I have an arduino UNO and RTC DS1307. I want to make an alarm that just displays on the serial monitor of arduino UNO. I can make the RTC show the right time on the serial monitor, however I want an alarm to go off on the serial monitor. Also, is there any way that I can change the alarm time on the serial monitor? Like I can type from my keyboard and the time changes?
One more question, How can I make arduino do multitasks using RTC. Like when the alarm goes off, it can run a small DC motor and also a Pizep Buzzer.
Please help me with this, as I desperately need a help :((
