Often when I have an idea for a new project, it will involve some components or circuitry that I have not used before. To be safe, I will sometimes design a smaller “test” board with just that component or circuit to test it out before I design the larger project. This is where the MegaMUX comes from. I wanted to test out the ADG732 multiplexer which is a 32 channel MUX. This means you can connect one output from the MUX, and select 32 other IO to connect to it. In this project I will show you how to connect the MegaMUX to an Arduino, and give you an idea of what you can do with it.”
