Timer Clock trigger

I have an arduino with a temperature/humidity sensor and a relay.
I use it to monitor a chameleon cage.
I also have a button widget that I can press to mist via the relay.
Is it possible to add a clock or timer widget that will automatically perform and on and off of the mister at a regular interval ?

Hi,

Yes however I recommend to apply the control strategy at the microcontroller and just use the platform to receive feedback, as the time that is running on certain cycle and to abort or start arbitrary a cycle, but the timer I think should be controlled at the microcontroller.

Hope this helps.
