I'm a total beginner in arduino, in fact i only just heard about it and started using it within the last month.
i'm using a DS1307 real time clock and i have successfully managed to input time and it reads it etc. I did this based on all your posts, searching playground, tutorials and examples.
My problem is actually setting an alarm time. I'm really struggling to find a code to follow and my plan is to set 2 alarm times based on 1 alarm time...
My goal is to set an alarm time using set potentiometer ranges; e.g turning a set pot range to set the alarm for 6am. (this is an extra element tho)
My priority: once this time has been set, i want it to count backwards 9 hours and set off a different alarm e.g. once 6am has been set, an alarm signal must go off at 9pm.
has anyone got any ideas as to how i might code this up?? Is it even do able??
