If we want to connect a pushbutton on the breadboard, where should it be placed?

• Only in the bus strips

• In the gap between the upper and lower sections of the terminal strip, so all 4 legs are connected

• In any available area

• In the upper left corner of the terminal strips

How many kinds of output can an arduino produce?

• DIGITAL ONLY

• DIGITAL and ANALOG

• ANALOG ONLY

• DIGITAL or ANALOG

What is the data type that hold a number value?

• VOID

• STRING

• INTEGER

• NUM

Why we need to put resistor on LED negative's leg?

• Just to extend the flow of electrical current to another hole

• To reduce/to balance the flow of electrical current in a circuit

• To dim the LED

• To adjust the intensity of the LED

What is the difference between void setup() and void loop() ?

• The code within void setup() runs only once, while void loop() repeatedly executes the code inside it

• Void setup() repeats the code and passes it to void loop()

• Void setup() is used to declare and repeatedly run any code, while void loop() is for initializing variables

• Both void setup() and void loop() execute the same code until it finishes

What is the name of the board?

• Arduino Nano

• Arduino UNO R1

• Arduino ESP32

• Arduino UNO R3

What category is this codeblocks?

• INPUT

• OUTPUT

• CONTROL

• MATH

Which one is the input component in this circuit?

• Ultrasonic sensor

• Resistor

• LED

• Arduino UNO

How we understand this code?

• Setting up the variable to read data from the ultrasonic sensor pins, with the condition that if an object is detected within 50 cm, the LED will turn ON; if not, the LED will turn OFF.

• Configuring the LED to stay ON whenever an object is detected.

• Distance of the object will be measured by the LED

• Read the distance of an object then the LED will stay ON

What is the equivalent meaning of HIGH in the codeblock?

• LOW

• OFF ONLY

• ON and 1

• OFF and 0
