Control 16 Channel Relay With Cd74hc4067 Multiplexer And Ardu 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. 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.
Interfacing Cd74hc4067 16 Channel Multiplexer With Arduino 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. 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. 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.
