By choosing the right hardware and software tools, developers can create powerful embedded applications using Python. Python is an excellent language for beginners to learn the basics of programming and develop fun and interactive projects.

In this article, we will walk you through the process of creating a Simon Says game on the BBC micro:bit, a popular development board that is perfect for prototyping and exploring circuits and coding.

Setting Up Your Environment

Before you start developing your Simon Says game, you need to set up your environment. To work with the BBC micro:bit, you need a few things:

– A BBC micro:bit

– A USB cable for power and to upload your code

– A computer or laptop to write your code

To start developing, you will need to install the Mu editor, an Integrated Development Environment (IDE) for Python that is specifically designed for use with the BBC micro:bit.

Once you have installed Mu editor, you can create a new project for your Simon Says game.

Displaying Instructions on the Screen

The Simon Says game involves displaying a pattern of colors on the LED matrix and asking the player to repeat the pattern. To display the instructions on the micro:bit screen, you need to write Python code to control the LED matrix, which is made up of 25 individually programmable LEDs. Here’s what the code looks like to display a red light on the first LED:

“`

from microbit import *

display.set_pixel(0, 0, 9)

“`

In this code, we import the microbit module and use the display object to set the brightness of the first LED to 9.

To display a pattern of lights, you need to use a loop to iterate over the pattern and display each color for a specified duration. Here’s an example code snippet that displays a pattern of red, yellow, green, and blue lights for 1 second each:

“`

from microbit import *

import time

colors = [“Red”, “Yellow”, “Green”, “Blue”]

durations = [1000, 1000, 1000, 1000]

for i in range(len(colors)):

if colors[i] == “Red”:

display.set_pixel(2, 2, 9)

time.sleep(durations[i] / 1000)

display.set_pixel(2, 2, 0)

elif colors[i] == “Yellow”:

display.set_pixel(4, 2, 9)

time.sleep(durations[i] / 1000)

display.set_pixel(4, 2, 0)

elif colors[i] == “Green”:

display.set_pixel(3, 3, 9)

time.sleep(durations[i] / 1000)

display.set_pixel(3, 3, 0)

elif colors[i] == “Blue”:

display.set_pixel(2, 4, 9)

time.sleep(durations[i] / 1000)

display.set_pixel(2, 4, 0)

“`

Running Your Code

Once you have written your code, it is time to run it on the BBC micro:bit. To upload your code to the micro:bit, connect your micro:bit to your computer using a USB cable, and click the “Flash” button in the Mu editor to upload your program.

Once your code has been uploaded, disconnect your BBC micro:bit from the computer and use the A button on the micro:bit to start the game. The game will display the pattern of lights on the LED matrix, and the player must repeat the pattern by pressing the same buttons.

If the player gets the pattern correct, the game will present a longer and more complex pattern on the LED matrix. micro:bit Resources
