A multiplexer of this type actually only acts as a switch 16 to a 1.
The 4 digital pins are used to set high or low, (binary Y0-Y15) to determine which input pin is connected to pin "Z".
The control input S0-S3 is set to low "logic level 0", the signal C0 is connected to the output Z. Multiplexer 16 Channels CD74HC4067 MUX/DEMUX features:
- Based on chip CD74HC4067
- Analog signal input: Y0-Y15, 16 channels
- Analog signal output: Z pin
- Digital input, channel control: S0-S3
- Module size: approx. 4 x 1.8cm
- Package includes:
* 1 x CD74HC4067 MUX connection module
* 2 x row of soldering pins

This module adapted for the arduino is a light sensor. The resistance of the LDR cell decreases as the light intensity increases.
On the contrary in a dark environment, the resistance of the LDR cell increases accordingly. Characteristic: - 3-pin connector: 1- GND
2- VCC
3- analog output - the voltage depending on the light
- Supply voltage: 3.3 V-5VDC
- PCB size: 19x15x8 mm
