Barometer for altitude in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to read the current pressure from the barometer sensor.

Drone Programming

pressure = barometer.[1]()

Drag options to blanks, or click blank then click option'

Aread_pressure

Bcalibrate

Cstart

Dget_altitude

Attempts:

💡 Hint

Common Mistakes

Using get_altitude() instead of read_pressure()

Calling start() which initializes but does not read data

The method read_pressure() reads the current pressure value from the barometer sensor.

2fill in blank

medium

Complete the code to convert pressure to altitude using the barometer's method.

Drone Programming

altitude = barometer.[1](pressure)

Drag options to blanks, or click blank then click option'

Acalculate_altitude

Bread_altitude

Cmeasure_altitude

Dget_altitude

💡 Hint

Common Mistakes

Using calculate_altitude() which might not exist

Using read_altitude() which is not standard

The method get_altitude() converts pressure to altitude based on sensor data.

3fill in blank

hard

Fix the error in the code to initialize the barometer sensor correctly.

Drone Programming

barometer = BarometerSensor([1])

Drag options to blanks, or click blank then click option'

Aport1

Bsensor_port

Ci2c_bus

Dgpio_pin

Attempts:

💡 Hint

Common Mistakes

Using gpio_pin which is for digital pins

Using port1 or sensor_port which are not standard identifiers

The barometer sensor is connected via the I2C bus, so i2c_bus is the correct parameter.

4fill in blank

hard

Fill both blanks to create a set of altitudes for each sensor reading above 100 meters.

Drone Programming

altitudes = {reading[1]2 for reading in readings if reading [2] 100}

Drag options to blanks, or click blank then click option'

A**

B>

C<

D+

Attempts:

💡 Hint

Common Mistakes

Using '+' instead of '**' for squaring

Using '<' instead of '>' in the condition

The code squares each reading (using **2) and filters readings greater than 100 meters.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping sensor IDs to altitudes above 50 meters.

Drone Programming

altitude_map = [1]: [2] for id, [3] in sensor_data.items() if [2] > 50}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using data as the loop variable instead of altitude

Mixing up keys and values in the dictionary comprehension

The dictionary maps id to altitude for each altitude item in sensor_data where altitude is above 50 meters.
