Control 16 Channel Relay With Cd74hc4067 Multiplexer And Arduino With 6 Arduino code to read temperature using cd74hc4067 chip and arduino with 6 wires to control 16 channel relay module. this code controls one channel at a time because of using multiplexing methode. wiring diagram for 16 channel relay with multiplexer. please click on image to enlarge. 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.
Control 16 Channel Relay With Cd74hc4067 Multiplexer And Arduino With 6 Learn arduino in 30 minutes (video): robojax l ?id=135this video shows you how to control one of 16 relay using the cd74hc4067 multiplexer chip. 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. 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. 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.

The cd74hc4067 is capable of more than reading analog signals. it can be uses in either direction. so you could connect sig to 5v, and then be able to switch the 5v to one of 16 channel pins if you needed to control 16 relays. it also works with serial.
