CD74HC4067 16-Channel Mux Breakout for Arduino 7.4v Model JSN-SR04T 2If you are running out of digital pins to control a 16 channel relay on your Arduino Uno? One thing comes in mind to upgrade to an Arduino Mega. But no, that's not the only workaround available. You could use a demultiplexer to increase the number of pins you can control or access by addressing them. This module uses a CD74HC4067, a multiplexer demultiplexer IC that can connect 16 other components using just 6 pins from Arduino. It can be as
