Diagnostic TEST Technology 9th

What is the "Brain" of an Arduino board?

• The analog ports

• The digital ports

• The microprocessor

• The oscilatior

How do you upload code to an Arduino UNO?

• Using the USB port

• Using the analog inputs

• Using the digital pins

• Using de digital write instruction

Given this code, the LED conected to 13 pin will be

• on for 2 seeconds.

• be off for 2 seconds.

• blinking on one second intervals

• off all the time.

If we use this progrma to control the wheels of a car. The car will

• Move forward.

• Turn to the left.

• Turn to the right.

• stop and do nothing.

What is the function of the analog ports in an Arduino board?

• To control the LED lights

• To read analog signals

• To upload code

• To power the board

Which component of the Arduino board processes the input and output signals?

• The microprocessor

• The USB port

• The power supply

• The oscillator

How does the digitalWrite function differ from the analogWrite function in Arduino programming?

• digitalWrite is used for analog signals and analogWrite is used for digital signals

• digitalWrite is used for digital signals and analogWrite is used for analog signals

• There is no difference between the two functions

• analogWrite is used for input and digitalWrite is used for output

If we want to reduce the current on a circuit to protect a LED, we use

• a multimeter.

• a capacitor.

• a resistor.

• a motor.

The soldering iron is used to

• cut holes into materials.

• soldering pieces of wood.

• soldering any kind of metal.

• soldering wires in electronic circuits.

From the following list of materials which is NOT a conductor for electricity?

• Gold

• Wood

• Iron

• Copper
