What is the primary purpose of using a pull-up or pull-down resistor with a switch on a Raspberry Pi?

• To increase the brightness of the LED
• To debounce the switch input
• To prevent current from flowing through the switch
• To protect the Raspberry Pi from overheating

Which GPIO pin mode is typically used when configuring a pin to read input from a switch on a Raspberry Pi?

• PWM mode
• Output mode
• Input mode
• Analog mode

In Python, which library is commonly used to control Raspberry Pi GPIO pins?

• RaspGPIO
• PiControl
• RPi.GPIO
• GPIO4Pi

Which type of switch maintains its state without the need for continuous pressure?

• Toggle switch
• Push-button switch
• Rocker switch
• Rotary switch

When a switch is pressed and held down, what is the state of the GPIO pin connected to it?

• High
• Low
• Floating
• It depends on the resistor used

How can you debounce a switch in software when reading its state on a Raspberry Pi?

• By adding a pull-up resistor
• By adding a capacitor to the circuit
• By ignoring the first few readings
• By using the time.sleep() function
