Python with MicroBits

MicroBit coding in Python

Now we will try and practice these concepts in Python for our MicroBits.

We'll do that by following an online user guide as per below.

https://microbit.org/get-started/user-guide/python/

The guide that you follow

https://python.microbit.org/v/beta

The editor that we'll use

Go through the list of subjects and for each subject read the text plus do at least one of the three tasks.

For each task, make sure you do Step 3!

More info about animal monitoring and tracking here

Practice task: Anti Poaching Collar

You now know how to program certain functions of your MicroBIT by using Python. Your task now is to make an anti poaching collar with the MicroBIT.

These are the requirements:

The device needs to send out a signal to another MicroBIT if the animal has not moved for 10 seconds.
The device needs to display a message continuously. The message needs to be;
- a HEART when the animal is safe (SAFE message)
- or a SKULL when the animal has not moved for 10 seconds (ALERT message)
The device needs to be able to be reset from ALERT to SAFE by pressing button A.
Code needs to be in Python and;
- - needs to be clear
  - needs to be logical
  - needs to have comments in it that are logical

EXTENSION

Make the alarm only go when it is light.
Make the MicroBIT collect data about the movements of the animal

Note to self: Teach trialing of components & testing outcome

Coding MicroBit to go underneath parachute

We will be dropping MicroBit on parachute off Walker block.

You should write code (in Python) to program the MicroBit to:

Start timing when released.
Stop timing when it hits ground.
Collect information about speed/ acceleration during the flight.
Time should display on LED screen when landed.
Info about flight should be able to be downloaded to device after flight for analysis.

BBC micro:bit - Tetris GameFor this challenge we are creating a game of Tetris to play on the BBC micro:bit. The game will be based on the following four shapes: The game will use the following inputs: Button A: Move current brick to the left Button B: Move current brick to the right Button A and B simultaneously: Rotate current brick clockwise Video Demo The game will use the LED screen which consists of a 5x5 grid of 25 LEDs. Each LED can be on (value: 9 for maximum brightness) or Off (value: 0) The side/borders of the grid will note be displayed. The Python code will use 2-dimension arrays (list of lists in Python) to store the main grid (7x5) and the current brick (2x2) To test this code you will need to use the Python Editor from the micro:bit website. Python Code Note: When testing this code, you may want to remove some of the #annotations especially if your micro:bit returns a "memory full" error.

BBC micro:bit - Traffic LightIn this challenge we are going to create and program a traffic light using lego bricks, leds and the BBC micro:bit. Check this video clip of the complete traffic light in operation: Step 1: Building the traffic light: Use a few lego bricks to build the traffic light. Include your LEDs within your blocks and connect their pins to the red and black electric wires. Make sure that you always connect the cathode of the LED (short leg, flat edge of the LED) to a black wire and use a blue or red wire for the other pin (anode). Step 2: Connecting the traffic light to the BBC micro:bit We recommend using crocodile clips for this step. Check the diagram below to make the right connections: Step 3: Programming the micro:bit Our aim is to reproduce the following traffic light sequence: Check below for the recommended code: In this solution we are adding a countdown when the green or the red light is on to inform the drivers who are waiting for the number of seconds redmaining before the
