This example demonstrates how to measure acceleration and calculate velocity during a free-fall experiment using a Micro:bit’s onboard accelerometer. It shows the detected vertical acceleration, the elapsed fall time, and the computed final velocity on the device’s LED display. The MicroPython code reads the accelerometer’s Z-axis via `accelerometer.get_z()`, converts the reading to m/s², and uses the kinematic formula `v = u + at` with a fixed gravity constant to estimate speed. The program triggers measurements when acceleration drops below -8 m/s², then scrolls the results as text.

Gráfica de Caída Libre

This visualization simulates a free-fall experiment using a micro:bit, displaying the measured fall time from a 4-meter drop in a line chart. It shows the relationship between elapsed time (in seconds) and fall duration, plotted across five time intervals. The code uses the micro:bit accelerometer’s `is_gesture("freefall")` to detect the start of the fall and calculates the time using `time.ticks_ms()`. It renders the chart with Chart.js on an HTML canvas, embedding the measured time as data points in the generated `CaidaLibreYupiii.html` file.

FALTA DE ATENCION AL RESPECTO DE LOS TRABAJOS REALIZADOS PARA OTRAS PERSONAS CODIGO FUENTE

This example displays real-time sensor data from a micro:bit, showing three-axis tilt and rotational changes on its 5x5 LED grid as a moving point. It also logs up to 100 timestamped records of tilt angles and rotation. The code uses the micro:bit’s `input.acceleration` and `input.compassHeading` APIs to calculate tilt and rotation, applying exponential smoothing with an `ALPHA` constant. Pressing button A toggles data recording, button B shows maximum tilt and record count, and AB sends the data via `serial.writeValue`.

Cálculo del Área de un Triángulo con Micro:bit

This example shows how a BBC micro:bit can be used as an interactive tool for calculating the area of a triangle. The MicroPython code uses the `microbit` module’s `display.scroll()`, `display.show()`, `button_a.is_pressed()`, and `button_b.is_pressed()` APIs to let a user incrementally set a base and height value, then displays the computed area on the device’s LED screen. The rendering approach is the micro:bit’s built-in 5x5 LED matrix, with button inputs serving as the only data source for the calculation.

README.md – MicroBit Tutor AI (MicroPython + micro:bit V2)

This gallery example shows an educational prompt and tutor system for teaching MicroPython to high school students using a BBC micro:bit V2. It presents a research activity where students investigate Python fundamentals, including `print()`, basic syntax, and the REPL, then compares standard Python with MicroPython code examples like `display.scroll()`. The material includes a 100-point grading rubric and describes a “Shell de Apoyo” support mode that breaks down errors with line-by-line explanations. The content is organized as a bilingual Markdown document with embedded images, aimed at guiding beginners from zero programming knowledge to hands-on microcontroller projects.

Microbit Assembly inline_code para practicas de ensamblador

This example shows a Micro:bit v2 assembly programming exercise that integrates ARM32 assembly instructions directly into MicroPython code. It demonstrates the use of the `@micropython.asm_thumb` decorator to access the Cortex-M4 processor's low-level functionality. The code includes a professional programmer's header with author, date, and device information, along with Spanish comments explaining each assembly instruction. It provides a functional example of adding two numbers using embedded assembly, designed to run in the MicroPython editor.

Actividad: ¡Creemos un Show de Luces con Microbits al Ritmo de la Música!

This example shows a collaborative music-synchronized light show using 42 BBC Microbits, where students program LED patterns that respond to a song’s rhythm via radio-frequency signals. The project adapts the Microbit “Fireflies” example, using MakeCode’s block-based editor and the radio API (`radio.sendNumber`, `radio.onReceivedNumber`) to sync all devices. It demonstrates shared-state coordination across multiple embedded devices, with each Microbit displaying unique blinking sequences that collectively form a unified visual performance driven by the chosen track.

Microbit para Taller de Cultura Digital usando Vibe Conding

This gallery example presents a Markdown-based teaching guide for a digital culture workshop, using a vibe coding methodology with the Micro:bit platform. It shows a structured table of 40 mini-projects organized into administrative categories such as time management, inventory control, personnel, finance, and customer service. Each row details a project name, its objective, estimated duration of one or two sessions, and a difficulty rating. The document is purely textual, outlining a pedagogical framework for rapid prototyping rather than visualizing data, with its layout structured through standard Markdown table syntax.

40 Misiones con IA (AI Create) para micro:bit – Actividades Educativas

This visualization presents a table of 40 educational AI activities for the micro:bit, pairing each mission with its objective, sensors, and labels. It shows a structured curriculum, from basic motion detection to cooperative multi-device tasks, while the static screenshot highlights the markdown source file that organizes the content. The rendering relies on the GitHub gist interface to display the raw markdown table, with no interactive code or data processing libraries involved. The visible data is the author’s curated list of sensor-based exercises, emphasizing how the built-in accelerometer, microphone, and light sensor can be used with AI Create to classify gestures, sounds, and environments.
