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.

What scenario is used to explain the concept of triggering multiple Arduinos with a single input?

How can you distribute milk from one bottle to multiple babies in the context of the Arduino project?

Describe the setup required to connect two Arduinos with a single push button.

What is the purpose of establishing a common ground between the two Arduinos?

What changes need to be made in the code to accommodate the input pull-up configuration?

Explain how the button press is detected in the Arduino code.

How does the LED respond when the button is pressed and released in the Arduino setup?
