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.

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.

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.

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.

Smiley Face Part II

This example simulates a digital circuit on a printed circuit board, allowing users to toggle switches and observe the resulting LED states. Built with React and p5.js, it loads board and component images, then uses JavaScript logic to model OR and AND gates alongside D flip-flops connected in a ring counter configuration. A periodic clock signal triggers state updates, and mouse clicks on switch positions flip their binary outputs, which are visualized as illuminated LEDs on the board.

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.

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.

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.

Gist for http://servuc.github.io/teaching/iot-4.html

This example demonstrates a mesh-network message-passing scheme for IoT nodes using the MySensors library and nRF24 radio modules. The Arduino sketch defines a single node (ID 10) that receives V_POSITION and V_LIGHT_LEVEL message types via the `receive()` callback, processes them, and can forward a path-end destination to adjacent nodes. It also sends a V_LIGHT_LEVEL acknowledgment to the gateway, with commented TODOs for gateway-driven light control and conditional forwarding logic. The setup and presentation routines blink an LED to signal initialization and radio handshake, while the main loop simply sleeps between transmissions.
