This example demonstrates how an ESP32 microcontroller detects button presses on an iTAG BLE device and triggers a sound response. The code uses the BLEDevice library to scan for the iTAG’s advertised address, connect to its FFF0 service, and register a notify callback on the FFF1 characteristic to monitor button state. When pressed, the callback increments a counter and sets a timer, while a second characteristic (FFF2) is prepared for sending sound commands. The sketch also includes serial logging and an LED indicator, with the connection logic managing reconnection via ESP.restart().

This example demonstrates a catalog of 45 MicroPython lab exercises for the Raspberry Pi Pico W, covering Bluetooth (BLE and classic HC-05) communication and OLED display control. Each exercise pairs a specific practice—such as BLE scanning, sensor data transmission, or relay control—with recommended Android/iOS apps and the primary lab function. The code references the `bluetooth`, `machine`, and `ssd1306` libraries to manage wireless links and render output on the SSD1306 or SH1106 display. The list is structured as a Markdown table, detailing the Bluetooth type, app, and purpose for each numbered activity.

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`.

This example demonstrates a Unity-based Bluetooth connection test that scans for bonded devices, attempts to open a serial RFCOMM socket, and sends a short command string. The code uses the `brab.bluetooth` library to access the Android BluetoothAdapter, enumerate bonded devices via `getBondedDevices()`, and create a socket with `createRfcommSocketToServiceRecord()`. It logs each step—device discovery, socket creation, connection, and data transmission—to both the Unity console and a UI Text element, while trimming old log lines after 32 entries. The visible behavior is limited to connection setup and a single write; no incoming data reading is shown.

Teaching :)

This example demonstrates a progressive Arduino teaching sequence, showing how to move from basic LED blinking to reading an analog sensor and handling button interrupts. The code uses the Arduino `pinMode`, `digitalWrite`, `analogRead`, and `attachInterrupt` APIs, with each sketch building on the previous one. It also includes JavaScript code using the `serialport` library to read Arduino serial output and test the connection via `yarn add serialport`. The visualization highlights both the physical wiring changes (LED pin, sensor pin, switch pin) and the serial communication between the Arduino and a computer.

JS Bin

This example connects a Spark Core IoT device to a web page, turning a div into a virtual LED and potentiometer display. The animation uses requestAnimationFrame to poll the device’s `potarValue` variable every 20 frames, updating a border-left width. Mouse enter and leave events call the `led` function via `device.callFunction` to turn the LED on or off. It demonstrates real-time hardware communication through the Spark JavaScript library, with the device’s status logged to the console.

This example shows a MicroPython learning activity where an ESP32 or Raspberry Pi Pico W sends prompts to the OpenAI ChatGPT API and displays the text response on an SSD1306 OLED display via I²C. The code uses `network.WLAN` for Wi-Fi connectivity, `urequests.post` to call the chat completions endpoint, and `SSD1306_I2C` from the `ssd1306` library to render the reply. The demonstration includes connection setup, JSON response parsing, and a simple text-wrapping routine for the OLED’s 16-character line width, with optional scroll or truncation for longer answers.

An Arduino-based MIDI sequencer displays a 16-step pattern on a 16x2 LiquidCrystal_I2C LCD, using custom bitmap characters to render empty, filled, and arrow-marked boxes for each step. The code reads two potentiometers via `analogRead` to control tempo and BPM, while a button toggles step values. MIDI clock pulses are sent through the `MIDI` library, and the display updates in the main `loop()`, showing the current pattern, BPM, and a moving arrow indicating the active step.

This example shows a simple Arduino program that reads a digital input from pin 2 and mirrors its state to an LED on pin 13. The setup configures the LED as an output and the input pin, while the loop continuously samples the switch every 100 milliseconds and writes the corresponding HIGH or LOW value using `digitalWrite`. It demonstrates basic I/O control and debouncing-free state reading with the Arduino `pinMode` and `digitalRead` APIs.
