Raspberry Pi and Arduino - Go to The Next Level - Push Button - Circuit

The video tutorial guides viewers through adding a push button to a breadboard, connecting it with a resistor to ensure proper functionality, and completing the circuit by linking it to a 5V power source and a digital pin. The tutorial also explains the role of pull-down resistors and provides a visual overview of the completed physical circuit setup.

Explain the difference between using an external resistor and the internal pull-up resistor of the Arduino.
