 Photo Resistor - Light Dependent Resistor - LDR:   Fit the module to Port 5 and the active buzzer to Port 6.   Bring the LDR towards a very bright light and the buzzer   will produce a tone.   This shows the resistance of the LDR is decreasing to a   value about 100 to 300 ohms.   The dark resistance will be as high as 100k.
