Using the Same Input to Trigger Multiple Arduinos

If you ever have a project using two or more Arduinos, it’s likely you’ll want them to work together.

Say for example you have one Arduino connected to an LCD shield, and another Arduino controlling an LED matrix.  You want both to do something when you press a single button – how can this be done?

It turns out to be extremely easy.  This video will describe in detail how to trigger multiple Arduinos with a single input.
