6th Grade ICT - Inputs and Outputs - CAA 2023

The purpose of the Motor Driver (or H-Bridge) in our project is to

• Control the amount of energy that goes to the Geared Motors

• Control the direction of movement of the Geared Motors

• Control the speed of movement of the Geared Motors

• All of the answers are correct

Digital Outputs such as 11, 10, 9 or 6 can be used to:

• Connect an input like the amount of light that comes from a photoresistor

• Turn on LEDs with different light intensities

• Give energy to the Geared Motors

• Connect a LED to GND

The range of values we can use to set Digital (PWM) outputs is

• 1 to 13

• High or Low

• Min: 0

  Max: 255

• Min: -255

  Max: 255

What does the following program do if connected to a LED?

• The LED is turned on forever

• Turns the LED on and off in a blinking pattern

• Starts with the LED turned off, and then turns it on with increasing light intensity.

• The LED is turned off forever

Which of the following programs would turn three LEDs on at the same time, and then turn them off at the same time?

• 
• 
• 
• 

What signals does the Arduino send to the Motor Driver (H-Bridge)?

• The speed and direction for moving the motors

• The intensity to turn on the LEDs

• The Arduino board is NOT connected to the Motor Driver (H-Bridge)

• All of the answers are correct

Which of these blocks can we use for controlling DIGITAL outputs?

• 
• 
• 
• 

True or False:

We refer to Analog outputs as outputs that can only be ON or OFF, and

We refer to Digital outputs as outputs that can have different values

• True

• False

True or False:

Both of this blocks turn off output 11

• True

• False

Why do we need to connect a 9 volts battery to the Motor Driver (H-Bridge)?

• Because the arduino needs 9 volts to work

• Because the Motor Driver needs 9 volts to work

• Because the Arduino can NOT provide enough energy to the motors

• Because the arduino CAN provide enough energy to the motors
