LDR based Sunset Lamp control Ready DIY Experiments Science Project Model STEM KIT (Assembled), 100% Tested

Abstract:
This LDR-Based Sunset Lamp Control Kit is designed for hobbyists, students, and educators to explore light-detection technology. Using an LDR, comparator IC (LM393), and relay, the circuit activates a lamp in the absence of light. This feature makes it perfect for automation experiments and educational purposes.

Key Features:

• Utilizes a readily available LDR for cost efficiency and simplicity.
• Designed for detecting light interruptions to control the lamp automatically.
• Operates on a standard 5V DC power supply for compatibility and convenience.
• Hands-on assembly experience to enhance learning and troubleshooting skills.

Working:
The circuit is powered by an LM393 comparator IC and an LDR as the light sensor. When light falls on the LDR, the lamp remains off. In the absence of light, the LDR stops conducting, and the lamp activates, providing a practical demonstration of automation principles.

Applications:

• Ideal for electronics hobby projects and STEM experiments.
• Perfect for automation and robotics-related demonstrations.
• Educational use in schools and colleges to teach light-sensitive circuits.

How to Assemble:

1. Read the included manual carefully and review the provided circuit diagram and PCB layout.
2. Identify components using resistor color coding and numerical values on capacitors.
3. Solder components to the PCB step-by-step, ensuring correct polarity for diodes and electrolytic capacitors.
4. Test the circuit by connecting a 5V DC power source and observing the lamp behavior when blocking or allowing light to fall on the LDR.

Testing Instructions:

• Adjust sensitivity using the variable resistor (R2).
• Ensure all connections are solid and the circuit operates as intended.
