Hello, Im very new to Arduino!
I have a two channel rotary shaft encoder and an LCD screen (16 X 2 used in 4 bit mode like the basic examples). I wish to display a timer on the screen (hours, minutes, seconds), set the time using the shaft encoder (turn clockwise to increase time, turn anti-clockwise to decrease time) in 5 second increments and when the timer times down from the programmed time and reaches 0, I wish to set a digitial pin high for a second and then reset the timer to the programmed time.
If possible it would be useful to increment the time in 5 second steps when the encoder is turned slowly and in 30 second increments if the encoder is turned quickly.
I really do not know where to start unfortunately, I have searched the forums and read various examples of timers and loaded some libraries to my IDE but I cannot find an example with the functions I need.
Any help would be appreciated
