Dark Sensor Circuit (LDR) – Circuit Diagram & Laser-Cut Template

Explore electronics through practical design and making.

This classroom-ready resource introduces students to a Dark Sensor Circuit using a Light Dependent Resistor (LDR). As light levels decrease, the circuit activates an LED, demonstrating how sensors and electronic components work together.

Ideal for practical electronics projects, the resource combines circuit construction with laser-cutting technology.

What's Included?

• Circuit Diagram (PDF) – Electronic circuit and component connections.
• Laser-Cut Template (PDF) – Circuit board design.
• CorelDRAW (CDR) – Editable laser-cutting file.
• DXF File – For compatible CAD and laser-cutting software.
• Completed Circuit Image – Reference photograph of the assembled circuit.
