Handheld Metal Detector Soldering Kit

Practise soldering while building a small handheld metal-detection circuit with audible and visual feedback.

✅ Hear the circuit's detection response - A buzzer gives an audible output when the assembled circuit detects metal.

✅ See the response as well - A red indicator adds visible feedback during the test.

✅ Connect assembly to an experiment - The DIY format lets you build the circuit before exploring its behaviour.

Build, check and try the detection circuit

Follow the component order and orientation in the instructions, checking solder joints before adding power. Once assembled, try a suitable metal object near the detector and compare how the response changes with position.

The project is intended for electronics learning and circuit practice rather than a certified security or utility-location task. Prepare the required batteries separately and use the completed circuit to explore its response under the supplied operating guidance.
