Introduction:
Expanding the input/output capabilities of an Arduino board is a common necessity for many projects, especially when dealing with a large number of analog sensors. The 74HC4067 16-Channel Analog Multiplexer Demultiplexer provides a convenient solution for handling multiple analog signals with a minimal number of pins. In this tutorial, we will explore how to interface the CD74HC4067 with an Arduino board, discuss the necessary pinouts and specifications, and provide code examples for implementing this versatile component in your projects.
Interfacing CD74HC4067 16 with Arduino:
The CD74HC4067 is a 16-channel analog multiplexer/demultiplexer that allows you to select one of 16 analog inputs and route it to a single output pin. This functionality is particularly useful when you need to interface multiple analog sensors or devices with an Arduino board that has limited analog input pins. By using the CD74HC4067, you can effectively increase the number of analog inputs available to your Arduino.
To interface the CD74HC4067 with an Arduino board, you will need to connect the control pins of the multiplexer to digital pins on the Arduino. The CD74HC4067 has four control pins: S0, S1, S2, and S3, which are used to select the desired channel. Additionally, you will need to connect the analog inputs and output of the CD74HC4067 to the corresponding pins on the Arduino.
