Virtual Labs

a: To limit current and prevent LED damage b: To increase LED brightness c: To make the button more responsive d: To convert analog to digital signals

a: By changing the wiring and updating the code b: By pressing the button twice c: By rebooting the Raspberry Pi d: It cannot be changed

a: To set the pin as input or output correctly b: To reduce CPU usage c: To improve LED brightness d: To enable Wi-Fi communication

a: It stays at 0V b: It changes from LOW to HIGH (or vice versa) c: It starts oscillating d: It turns into an analog signal

a: The LED will never turn ON b: It may still work depending on connection to ground or VCC c: It will damage the Raspberry Pi d: The button will act as an analog sensor

a: By using a loop that reads the GPIO input pin repeatedly b: By sending an interrupt signal to the Pi c: By only reading the pin once at startup d: By using Wi-Fi polling
