Using the Same Input to Trigger Two Arduinos

This tutorial explains how to use a single input to trigger multiple Arduinos simultaneously. It begins with an analogy to illustrate the problem and then guides the viewer through setting up a circuit with two Arduinos and a push button. The video covers the necessary coding in the Arduino IDE to control LEDs with a button press. Finally, a demonstration shows the circuit in action, and the tutorial concludes with additional learning resources.
