Push Button with Arduino

What is the primary function of the button in the demonstrated Arduino circuit?

• To provide power to the LED.

• To act as an output to control the Arduino.

• To serve as an input to control the LED.

• To measure the voltage across the circuit.

What is pseudocode used for in programming?

• To write algorithms using everyday language without worrying about exact syntax.

• To create graphical representations of algorithms using symbols.

• To directly program an Arduino board with specific commands.

• To simulate circuits in a web browser.

What is the danger of directly connecting the button to 0V without a resistor when the button is pressed?

• It will cause a very large amount of current to flow, potentially damaging components.

• It will prevent the LED from turning on.

• It will cause the Arduino to read an incorrect voltage.

• It will make the button unresponsive.

What is the primary purpose of a pull-down resistor in this circuit?

• To ensure the input pin reads a defined low (0V) when the button is not pressed.

• To increase the current flowing through the button.

• To protect the LED from overcurrent.

• To provide a path for 5V when the button is pressed.

• Yes

• No

How can you modify the code to make the LED turn on when the button is not pressed and turn off when the button is pressed?

• Switch the HIGH and LOW values in the digital write commands.

• Change the condition in the if statement from checking HIGH to checking LOW.

• Both of the above.

• Neither of the above.
