Output

In this Sunset Indicator Circuit activity, the LDR (Light Dependent Resistor)
detects the level of light. When the light dims (like during sunset), the LED is
triggered to turn on, indicating low light levels. The ADJ module helps control

the sensitivity of the LDR.

Concepts

1. Light Sensing and Circuit Response: You will explore how an LDR
changes its resistance based on the amount of light it detects. This introduces
