I am trying to build a circuit where two separate circuits turn on with one pushbutton press. One input would be 5V and one would be a ground. Is there an easy way to do this?
An easy way to do this would be give us more details about what you're trying to do. At the moment I don't understand quite what you're asking for; therefore I can't give you guidance.
Thank you for the replies. The project consists of two arduinos, one sound board, one uno. The soundboard needs to be triggered by connecting the ground to a trigger input and the arduino uno needs to be powered at the same time as the soundboard trigger button. See diagram attached, hopefully not to confusing, as I am not too experienced with diagramming.
