Thank you for all your answers. The actual code in the example isn’t real code I’m using, hence the syntax errors here and there also sorry if I have used any misleading vocabulary. Generally take what it written to mean what it means in English not code.
Setting cycle via LCD will be possible as the LCD nokia board I use has a built in joystick to handle user inputs.
I’m really just trying to get my head round what needs to go where when I write the code and how the main loop gets interrupted to perform desired tasks.
This is where I’m at so far. It compiles but doesn’t do anything yet and I’m waiting for some parts to arrive to build another controller to develop on (the current one I have is usig different code and busy controlling my reef lights).

Purpose: - to improve upon the work of the Krusduino project
Written for: - Duemillanove based Krusduino (Temp probe removoed) with Chester's Garage LED Shield v2
Aims: - to provide smoother ramp up and ramp down functions
- to allow setting of photoperiod via LCD (removes the need to load from eeprom for cleaner codebase)
- to allow setting of ramp times (removes the need to load from eeprom for cleaner codebase)
- to provide 4 channels with graphical representation
