A pack of components to build 10 light sensors, ideal for class projects with students working in small groups.
The general-purpose light-sensing circuit uses a miniature light dependent resistor (LDR) to detect changes in the level of light and switches the LED on or off accordingly. The sensitivity of the circuit can be set by adjusting a potentiometer.
