Based around a light dependant resistor and a transistor, this project introduces the student to how an input device can be used to switch a transistor on or off. The project can be used to demonstrate how security/street lights work when the light level changes. A series of worksheets take the student through the design process stage by stage, and clearly explain how the circuit works. The kit includes variable resistor, LDR, transistor, LED, resistors and battery snap. Please note the PP3 battery is not supplied.
