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.

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.

Gist d6881ff1705f8c86cc3c3b09327ad069

This Arduino sketch demonstrates a color-fading light sequence across three LEDs using the `analogWrite` API with pulse-width modulation values from 0 to 255. The `loop` function cycles through pairwise transitions—red to green, then green to blue, then blue to red—with `lightMe` incrementally raising one channel’s brightness while lowering another over ten steps, pausing via `delay(250)` between adjustments. Each pair ends by setting one LED fully off and the other fully on, revealing a continuous, repeating crossfade effect.

Coding Adelante: Challenges

This example shows a progression of coding challenges for learning JavaScript, starting with basic functions and building up to object-oriented programming. The gist presents a series of exercises that ask the reader to implement functions like `hello`, `multiply`, `sum`, `isEven`, and `isDivisible`, each with sample inputs and expected outputs shown in commented code. The visible API is plain JavaScript, using console output via `console.log` and standard function declarations. The examples gradually introduce arrays, conditional logic, and higher-order patterns, with the source being a single Markdown file from a gist. The rendering approach is purely text-based, with code blocks and comments that illustrate function behavior without any graphical or external library dependencies.

Arduino shutter

This Arduino sketch operates an automated window shutter based on light and manual switch inputs. It shows a control loop that prioritizes an automatic daylight response, moving the shutter fully up or down when light conditions change, while also responding to physical wall switches with partial movements. The program uses the Arduino core library’s `pinMode`, `digitalRead`, and `digitalWrite` functions for I/O, along with `attachInterrupt` for switch detection and `Serial` for status logging. The logic employs simple state comparison to distinguish between sun and moon conditions, triggering relay outputs for up, down, or stop actions with predefined time delays.

arduino test

This example demonstrates a live sensor-data visualization using the Firmata library to communicate with an Arduino board over a serial connection. The code establishes a board connection via `firmata.Board` and logs a message once the link is ready, though it does not yet render any visual output. The focus is on the initial data-acquisition stage, where raw input from the board would be captured and prepared for future graphical mapping. The visualization’s rendering approach remains unspecified, as the current code only handles the communication handshake.

Express server and serial port reading

This example shows a live data pipeline that reads sensor values from an Arduino over a serial port and exposes them through a simple HTTP endpoint. The Arduino sketch generates random temperatures between -5 and 15 degrees Celsius every five seconds and prints them to the serial monitor. Two JavaScript libraries, `serialport` and `express`, handle the communication: the serial port parser (`serialport.parsers.Readline`) captures each line of incoming data, while the Express server responds to root requests with the latest stored value. The result is a minimal web page displaying the current temperature reading.

25aUltimoLDI10prg

This example presents a collection of ten educational MicroPython programs for the Raspberry Pi Pico W, each integrating a digital or analog sensor with an SSD1306 OLED display. The programs demonstrate real-time data visualization, such as a weather station using a DHT22 sensor, and include a custom SSD1306 driver class for I2C communication. The code relies on the `machine` module’s `Pin` and `I2C` classes, along with the `dht` library, and implements a basic 8x8 pixel font for on-screen text rendering. The project targets the Wokwi simulator or physical hardware.
