Figure 5 - Complete set-up of the sunlight simulation (Fingerbot).
To facilitate a comparison, we established both a control and Figure 7. This simulated schedule aims to replicate natural

from 0:700hrs to 19:00 hrs, mimicking the lighting schedule
of the fish farm. The experimental set-up of prototype 1 is shown in Figure 8.
Meanwhile, the team gradually adjusted the light intensity
for the prototype set-up, starting at 0:700 hrs. As illustrated
in Figure 6, the lights were set to switch on dimly at 0:700
hrs and gradually increase in intensity every 30 minutes until
reaching maximum brightness at 11:00 hrs. This interval
was chosen to replicate the natural progression of sunlight.
Subsequently, the lights remained at maximum intensity for
1 hour and 30 minutes to simulate the afternoon sun.
Following this period, the light intensity gradually decreased
from 12:30hrs to 18:00hrs at 30-minute intervals, imitating
the gradual transition towards evening. Finally, the lights
were programmed to switch off at 19:00 hrs, as shown in
