Cd74hc4067 Arduino

Learn how to use a CD74HC4067 multiplexer to read 16 analog sensors with 4 digital pins. See the schematic, code example and binary table for this easy project.

Arduino library for the CD74HC4067 mux. Connect the four control pins to any unused digital or analog pins. Connect the common pin to any other available pin. This is the pin that will be shared between the 16 channels of the CD74HC4067. The 16 channels will inherit the capabilties of the common pin.

Arduino Interfacing With CD74HC4067 16-channel MUX The CD74HC4067 is a 16-channel multiplexer. This module is used when you need to monitor multiple sensors or input devices on a single port. This is helpful in devices where there are only 1 or few analog pins. The Arduino has 6 analog pins, which m

CD74HC4067 Multiplexer Arduino or any compatible microcontroller Sensors or input devices e.g., potentiometers, buttons Jumper wires and a breadboard Basic Steps Connect Power Link the VCC pin to 5V or 3.3V depending on your Arduino version and GND to ground. Connect Control Pins Attach S0-S3 to digital pins on your microcontroller.

Arduino CD74HC4067 Analog Multiplexer. An Analog Multiplexer Switch is a device that operates exactly like a digital multiplexer in terms of the core functionality of routing a signal to multiple outputs. However, an Analog Multiplexer does this for analog signals not digital exactly like the built-in analog switch inside an ADC in any microcontroller.

CD74HC4067 multiplexers are inexpensive devices. We can find them for 0.80 from international sellers on eBay or AliExpress. Assembly diagram. The connection is simple. On one hand, we power the CD74HC4067 by connecting Vcc and Gnd respectively to 5V and Gnd on Arduino. We also connect the chip EN to 5V, to activate the CD74HC4067.

This circuit features an Arduino Micro connected to three CD74HC4067 multiplexers, which are used to expand the number of analog inputs. Multiple potentiometers and toggle switches are connected to the multiplexers, allowing the Arduino to read various analog signals and switch states for further processing.

You've successfully interfaced the CD74HC4067 multiplexer with Arduino.
