New Alarm light flash app

Hi
I have no idea if this is the right section, I am trying to design a app that will flash certain lights in my house on given days at given times to remind someone that they need to leave for work ( not me by the way).
I tried the flasher app, but that will run every day; the smart app cant fulfill this;
I must admit I did try my hand at modding the flasher app, but ran into loads of validation errors. I admit I am not young enough to start learning a complete new language.

Any assistance appreciated
