16 Channel Analog Multiplexer Cd74hc4067 For Arduino Arduino Diy

16 Channel Analog Multiplexer Cd74hc4067 For Arduino Arduino Diy Cd74hc4067 16 channel multiplexer pinout. this module has 24 pins: vcc: module power supply – 5v. gnd: ground. en: enable pin (active low) s0 3: selecting one of 16 analog input pins as the final output signal. c0 15: analog inputs. sig: output signal. you can see the pinout of this module in the image below. 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 means we can monitor a maximum of 6 sensors. with the help of cd74hc4067, we can monitor 16.

Interfacing Cd74hc4067 16 Channel Multiplexer With Arduino Now, we’re ready to create our first arduino project with the cd74hc4067 analog multiplexer. in this example project, we’ll use the cd74hc4067 to extend 1 analog input pin of the arduino (a0) and make it accept up to 16 different analog inputs. for the sake of circuit simplicity, i’ll only use 4 analog channels of the cd74hc4067 module. 3 1033×576 91.6 kb. wawa october 27, 2018, 8:30pm 2. a 74hc4067 is a selector switch with 16 positions. it connects a common pin to one of the 16 inputs outputs (a switch works both ways). four control pins are needed to generate the binary numbers 0 15 to select the position of the switch. Step 1: using the 74hc4067. at this point you should download the data sheet, as we refer to it through the course of the article. the first thing to note is that the 74hc4067 can operate on voltages between 2 and 6v dc, which allows use with 3.3v and 5v microcontrollers and boards such as arduino and raspberry pi. (in the arduino software high is the same as1 & low is the same as 0). after it sets the pins so that sig is connected to the correct channel, it then reads analog 0 (where sig is connected to) and returns that value. so all you need to do is something like this. for more detail: muxing around with the cd74hc4067 arduino.
