Project: greenhouse lighting

The greenhouse gets its own control: grow lights on a schedule, a lamp for the harvest and a lever for permanent light while you work inside. Everything from this week in one chip.

The setup#

All grow lights have the same name. A single sbn switches them together, whether there are two or twenty. The trays need no name, lbs reads them by their type.

Milestones#

1. Light on schedule: in every period of PERIOD ticks the grow lights are on for the first ON ticks, then off.
2. Ripeness: the lamp “Ernte” lights up as soon as a plant is ripe. The display “Reife” shows the progress of the most advanced plant in percent.
3. Permanent light: if the lever is on, the grow lights stay on. The schedule keeps running in the background.
4. Failure: if the trays are missing, the display shows 0 and the lamp “Ernte” is off. If the lever is missing, the schedule applies.

Times for the test#

In the test the times are short: PERIOD 30 and ON 20 ticks. In the game you enter your real plan, for example 7200 and 4800 for one hour with 40 minutes of light.

define PERIOD 30 # ticks per light period (in game e.g. 7200)
define ON 20 # light ticks per period (in game e.g. 4800)
move time 0

The move time 0 sits before the start label. That way the plan starts cleanly from the beginning after every upload.
