Raspberry Pi For Beginners - 2022 Complete Course - Add a Push Button to Your Circuit

This tutorial guides you through safely shutting down a Raspberry Pi, preparing the circuit by removing the SD card, and adding a push button to the hardware setup. It details the components needed, such as resistors and wires, and provides step-by-step instructions for connecting the push button to the circuit using a breadboard. The tutorial concludes with finalizing the setup by connecting the button to GPIO and powering the Raspberry Pi back on.

What is the first step before adding a push button to your Raspberry Pi setup?

• Ensure the Raspberry Pi is correctly shut down

• Connect the Raspberry Pi to a monitor

• Check the internet connection

• Install the necessary software

Which components are needed to add a push button to the circuit?

• An LED and a switch

• A transistor and a relay

• A capacitor and a diode

• Two resistors and three wires

How should the push button be positioned on the breadboard?

• With all legs on the same line

• Between two parts of the breadboard

• Directly connected to the power line

• On the left side of the breadboard

What is the purpose of connecting the push button to the blue line on the breadboard?

• To connect it to the ground

• To connect it to the power supply

• To connect it to the LED

• To connect it to the GPIO

Why is the 3.3V line used for the push button?

• To connect directly to the LED

• To save power

• To allow for additional components to be connected

• To ensure the button is always on

Which GPIO pin is used to connect the push button?

• GPIO #4

• GPIO #26

• GPIO #22

• GPIO #17

What should you avoid when connecting the GPIO pin?

• Connecting it to the LED

• Connecting it to the ground pin

• Connecting it to the power line

• Connecting it to the resistor
