Total questions: 30
Worksheet time: 54mins
Which example shows a small LAN?
An isolated computer with no Wi‑Fi card
Home network with one user and devices
Global network linking many continents
Two phones using Bluetooth briefly
Which connected device would most likely be part of a modern LAN at home?
Analog wall calendar
Smart TV or thermostat
Gasoline engine piston
Paper-based filing system
How do you set the message on the LAN broadcast block?
Change the router password first
Type a command in the console
Restart the device after pairing
Click to set the message name
Why is Upload mode specifically mentioned before transferring programs to CyberPi 1 and 2?
It shares variables between devices only
It disables Wi‑Fi for security reasons
It compiles and stores code to run without a PC
It converts blocks into image files
If CyberPi 2 does not play the sound after receiving a message, which part of the second script should be checked first?
Play hi until done block
Button A pressed block
LAN password block
Brightness control block
What action is suggested if you only have one mBot2?
Ask a friend to borrow theirs
Skip the second device
Use a Bluetooth speaker
Replace it with a webcam
Which statement best describes the sequence for adding devices?
Create sprites, paint backgrounds, then record audio
Pair Bluetooth headphones, then test speakers
Install drivers, restart PC, then connect Wi‑Fi
Open mBlock5, add a CyberPi, then add another
Which event should trigger the LED display after a broadcast is received?
When program starts
When button B pressed
When receiving broadcast on LAN
When message equals zero
If two students accidentally use the same message address, what is the most likely outcome?
Devices stop connecting to Wi‑Fi entirely
Messages are ignored by the sender device
Programs interfere because broadcasts overlap
LEDs become dimmer on both devices
Which statement is true about CyberPi receiving LAN broadcasts?
It can receive broadcasts from devices on the same LAN
It receives only messages sent by the internet cloud
It can receive messages even when LAN is disconnected
It receives messages only from paired Bluetooth devices
A program needs to send a sensor reading over LAN. Which is the best approach?
Use when receiving message to trigger the send
Use Bluetooth broadcast without message value
Use router settings to convert reading to text
Use broadcast message with value set to the reading
Which action triggers CyberPi 2 to show the value on its screen in the example? (Lesson 1)
Pressing button A on CyberPi 1
Pressing button B on CyberPi 2
Restarting both CyberPis again
Selecting a different Wi‑Fi network
What type of block is “LAN broadcast message value received”?
A reporter block requiring data
An event block with no inputs
A command block acting alone
A control block for loops
Which event block should CyberPi 2 use to react to incoming LAN messages?
When button A is pressed locally
When timer reaches a certain value
When receiving message broadcast on LAN
When device orientation changes
What does the note suggest when using a router for communication?
Disable Wi‑Fi to prevent lag
Rename networks for each device
Use separate LANs for stability
Connect all CyberPis to the same LAN
If CyberPi 2 is not displaying the value, which is the best first step to troubleshoot?
Turn off the router permanently
Reduce pixel size of the text
Rewrite the entire program again
Check both are on the same connection / (broadcast message)
Which action starts the program that gathers and sends data? (sample project on the lesson 2)
Pressing button A on the CyberPi
Pressing button B on the CyberPi
Powering on the first mBot2
Connecting to Wi‑Fi on the robot
Which action stops the data collection loop before sending the last value? (sample project on the lesso
n 2)
Pressing button A on the CyberPi
Turning off both mBot2 units
Disconnecting the LAN cable
Pressing button B on the CyberPi
What is sent after the stop condition is met in the program logic? (sample project on the lesson 2)
The last distance value is broadcast on LAN
All recorded values are saved to memory
A stop signal is sent to both robots
The display is cleared on CyberPi2
In the sample project on the lesson 2, variable A is repeatedly set to which value?
Ultrasonic distance in centimeters
Button A press duration in ms
Motor speed in percentage
Battery voltage in volts
What must be consistent between CyberPi and CyberPi2 for LAN broadcast to work correctly?
Brightness level
Wi‑Fi password only
Same address setting (same broadcast message)
Ultrasonic frequency
Which distance range triggers a red light on CyberPi B? (this is the exercise on the lesson 2)
5–10 cm
8–12 cm
0–4 cm
Over 10 cm
You want CyberPi B to display blue when the distance is exactly 10 cm. Which rule applies?(this is the exercise on the lesson 2)
10 cm is in 5–10 cm
10 cm is over 10 cm
10 cm is under 5 cm
10 cm is not defined
