It's the practical way to move from theory to observation without hunting for loose components.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYour students will assemble a multi-sensor testbed where every block responds to a different physical quantity. They will bias an LDR for light, balance a thermistor in a voltage divider, pulse an IR LED and read the photodiode, power a condenser mic through a transistor amplifier, detect body touch on copper pads, trigger a tilt-switch circuit, activate a reed switch with a magnet and measure a Hall effect sensor's output-all using common resistors and transistors.
