ICT - 6th Grade 2nd Term Exam

One of the purposes of the Motor Driver (H-Bridge) is:

• Connect to a battery to give energy to the motors

• Control the light intensity of the LEDs

• Give energy to the Arduino Board

• Detect the presence of an obstacle by sending waves

2. If you need to program and ultrasonic sensor, and you to create a variable to store the information from the sensor, how should you call the variable?

• Speed

• Time

• Distance

3. How does this program work?

• It turns on a led and leaves it on for a long time and then turns it off.

• It turns on a led and leaves it on for 5 seconds then turns it off for 5 seconds.

• The program doesn't work

7. True or False: this program shows how a sprite identifies the distance using an ultrasonic sensor

• True

• False

8. Which of these programs is the best option for turning a LED on using an ultrasonic sensor?

• Option A

• Option B

• None

In Animation, what is Frames-per-second (FPS)?

• A program we use for creating animations

• A type of drawing for animation

• A measurement of the speed of the animation

• The name of an animation.

How can you make this animation look "Smoother" (more fluid)?

• By decreasing the FPS (speed) of the animation

• It is not possible to make an animation smoother

• all options are correct.

• By adding more frames with more drawings of the animation

Select the three "classifications" or types of connections we use on a Motor Driver

• The connections between the Arudino and the Motor Driver

• The connection between the Motor Driver and the LEDs

• The connection to a power source such as a battery

• The connections to the motors.

In the Arduino Uno, what are Digital PWM Outputs?

• Outputs that can only be a value between 0 and 255

• Connections to the Ultrasonic Sensor

• Outputs that can be HIGH and LOW, or a value between 0 and 255

• Outputs that can only be HIGH or LOW

What do we usually connect LEDs to?

• To inputs in Arduino, since the LEDs send information to the Arduino

• To outputs in Arduino, since the Arduino sends a signal to the LEDs

• To 5v, so the LEDs have enough energy to turn on

• To the computer through a USB cable
