Plotter mural. The code. LibraryTutorial. This document explains how to create a library for Arduino. It starts with a sketch for flashing Morse code and explains how to convert its functions into a library. This allows other people to easily use the code that you've written and to easily update it as you improve the library. For more information, see the API Style Guide for information on making a good Arduino-style API for your library. We start with a sketch that does simple Morse code: int pin =13; void setup(){ pinMode(pin, OUTPUT);} void loop(){ dot(); dot(); dot(); dash(); dash(); dash(); dot(); dot(); dot(); delay(3000);} void dot(){ digitalWrite(pin, HIGH); delay(250); digitalWrite(pin, LOW); delay(250);} void dash(){ digitalWrite(pin, HIGH); delay(1000); digitalWrite(pin, LOW); delay(250);} If you run this sketch, it will flash out the code for SOS (a distress call) on pin 13.

The sketch has a few different parts that we'll need to bring into our library. Let's start turning the sketch into a library! #endif #include <Morse.h> KeyboardAndMouseControl. This example illustrates the use of the Mouse and Keyboard libraries together. Five momentary switches act as directional buttons for your cursor. When a button is pressed, the cursor on your screen will move, and a keypress, corresponding to the letter associated with the direction, will be sent to the computer. Once you have the Leonardo, Micro or Due programmed and wired up, open up your favorite text editor to see the results.

NB: When you use the Mouse and Keyboard library functions, the Arduino takes over your computer's cursor! To insure you don't lose control of your computer while running a sketch with this function, make sure to set up a controller before you call Mouse.move(). Hardware Required Arduino Leonardo, Micro or Arduino Due board 5 pushbuttons 5 10k ohm resistors hook-up wires breadboard Software Required Any text editor Circuit Attach one end of the the pushbuttons to pins 2, 3, 4, 5, and 6 on the board.

To get it recognized as a keyboard, all you need to use is the Arduino Keyboard library, and conditional statements. Before we start with the conditional statements, we need to setup the pins.

We only need this to run once, so put this into the void setup. Start with pinMode(PinNum, INPUT_PULLUP); This tells the Arduino that the PinNum is expecting an input, and that it adds a pullup resistor (so that we don't need to wire any in the hardware) The input pullup has 2 states, LOW and HIGH. The Arduino will read LOW on a pin when it is connected to Ground (GND) and will read HIGH when it is disconnected. Starting with the basics, we use conditional if statements to find if the key was pressed. For the code for the keyboard, import the Keyboard library. To import a key, just put a apostrophe around both sides to indicate that it is a character. The code will look something similar to this: Building a small (Gaming-) KeyPad for StarCraft 2. A month ago or so I started playing StarCraft 2 again. I'm not really good at it, actually, but it's fun to play with my friends. I've never ever got used to the hotkeys, most of my refuse to practice.

As an engineer I've tried to solve problems by creating tools, not to practice stupid routines. The grind hotkey system seems a good idea, but it if you think about it, there is a serious design fault. As a right-handed person you have to use the left hand for the hotkeys. The grid on the screen is on the right side and the most used keys are on the left. This means you have to use your little finger for the most common actions - that's not very comfortable. Another thing is that switching between right and left shift is not very intuitive. My idea was to mirror the grid on a special keypad. It's totally stupid to shift the hole grid to the left. After thinking about this I wanted to try it. First I salvaged some old Cherry-MX keys from an old keyboard. The case is fully 3D printed. DIY Shortcut Keyboard.

Working with CAD programs involves focusing on the task at hand and keyboard shortcuts can be very handy. Most software packages allow the user to customize these shortcuts but eventually, certain complex key combination can become a distraction. [awende] over at Sparkfun has created a Cherry MX Keyboard which incorporates all of the Autodesk Eagle Shortcuts to a single 4×4 matrix. The project exploits the Arduino Pro Mini’s ability to mimic an HID device over USB thereby enabling the DIY keyboard.

Pushbuttons connected to the GPIOs are read by the Arduino and corresponding shortcut key presses are sent to the host machine. Additional functionality is implemented using two rotary encoders and the Teensy encoder library. The first knob functions as a volume control with the push-button working as a mute button. The project can be extended to be used with other computer software such as Gimp and the keys may be replaced by capacitive touch sensors making it more sturdy. S Raspberry Pi Lesson 10. Stepper Motors.

Stepper motors fall somewhere in between a regular DC motor (Lesson 9) and a servo motor (Lesson 8]). They have the advantage that they can be positioned accurately, moved forward or backwards one 'step' at a time, but they can also rotate continuously. In this lesson you will learn how to control a stepper motor using your Raspberry Pi and the same L293D motor control chip that you used with the DC motor in Lesson 9. The Lesson will also show you how to use an alternative driver chip, the ULN2803 For this project, it does not really matter if you use a L293D or a ULN2803. The motor is quite low power and suffers less from the surges in current than DC motors and servos (which use DC motors).

Stepper Tutorial. L293D - Commander des moteurs depuis Arduino. Description Le L293D est un double Pont-H est destiné aux hobbyistes désireux de commander des moteurs de faible puissance (600mA par pont, 36 volts max). Ils sont parfait pour découvrir le fonctionnement et le raccordement d'un pont-H et conviennent parfaitement pour de petits véhicules téléguidés. Si vous avez besoin de contrôler des moteurs plus puissant, nous conseillons le breakout L298 qui est un pont-h supportant un courant de 2 ampères. Ce petit pont-H est déjà équipé (en interne) de diodes en roue libre, ces diodes sont utilisées pour protéger le pont H des effets transitoires. Ce Pont-H peut donc être utilisé directement avec un Arduino sans nécessiter de matériel complémentaire. Un tutoriel sur le L293D Nous avons préparé un tutoriel TRES détaillé sur le L293D et sa mise en oeuvre avec Arduino.

Desktop CT and 3D Scanner With Arduino: 12 Steps (with Pictures) CT scanning requires a source of radiation (e.g. x-rays or light) on one side of an object and detectors on the other side. The amount of radiation that makes it to the detector depends on how absorptive the object is at a particular location. A single image acquired with this setup alone is what produces an X-ray. An X-ray is like a shadow, and has all the 3D information projected into a single 2D image. To make 3D reconstructions, a CT scanner acquires X-ray scans over many angles by either rotating the object or the source-detector array. The images collected by a CT scanner are called sinograms, and they display absorption of X-rays through one slice of the body vs. angle.

The same principle is applied for the optical CT scanner with a camera acting as the detector and the LED array acting as the source. Photogrammetry requires the object to be illuminated from the front. Scanner laser 3d it. Hackster. Introduction Hi. Thank you for showing Interest in this project.

CNC avec Arduino et GRBL. Je vous propose de vous donner quelques tuyaux pour la réalisation d'une CNC avec Arduino et GRBL. J'ai déjà réalisé ma CNC, mon graveur laser et mon imprimante 3D e vous mettrait donc quelques photos. La mécanique Concernant la partie mécanique, je pense que vous avez tous votre idée et surement un budget. Voici des idées de montage Ma première CNC bois, alu et tôle (ne faites pas attention au bordel lol) Pour la réalisation de celle-ci, j'ai utilisé des coulisses de tiroirs supportant 35Kgrs, des tiges filetées standard de 8, des moteurs NEMA 23 basiques et des 2M542 et drivers.

Quelques réalisations avec cette machine Voici quelques détails mécaniques de ma dernière fraiseuse CNC Désolé pour les clopes lol !!! J'éspère que cela va vous donner des idées !!! L'électronique Le choix concernant cette partie est assez délicat car les drivers doivent supporter la puissance des moteurs, certains drivers ont tendance a sauter des pas lorsque la machine force un peu. Le schéma de câblage Le typon. Arduino Mini CNC Plotter Machine from dvd drives - All. In this project I will show you how to easily build your own low-cost Arduino Mini CNC Plotter! This project is an update from my previous cnc, with better construction and with more accuracy. I decided to make this detailed guide to help you make it on a few easy steps. Small description: For the X and Y axes we will use two stepper motors and rails from dvd/cd drives and for the Z axis we will use a small servo motor that moves the pen up and down.

For the mounting base we will use a small piece of plexiglass. You can easily attach a pen (or pencil) - irrespective of its thickness - on it. The Arduino-based circuit is using the ATmega328 microcontroller, two L293 motor driver ICs and an usb to serial module. You can also use an Bluetooth module (e.g. Q & A and updates here: More cool Arduino projects can be found here: Watch presentation video below and proceed to next step! Decoding and sending 433MHz RF codes with Arduino and rc-switch | Wes's Blog.

In this tutorial I’ll show you how to use an Arduino to decode signals from RF remotes, and re-send them to remotely control some mains switches and a garage door. RF transmitter and receiver modules connected to the Arduino using a solderless breadboard and jumpers Arduino – I’m using an Arduino Uno Rev3.433.92Mhz RF Transmitter and Receiver Pair – I got mine from eBay for the ridiculously cheap price of $1.45: Transmitter Model No: MX-FS-03V (marked XD-FST) Receiver Model No: MX-05V (marked XD-RF-5V) They work just fine – the main problem is that there is no datasheet or documentation available. Some basic specs are available on but that’s about it. Similar modules should also be available at your local electronics shop e.g. Connect transmitter and receiver to Arduino The rc-switch wiki has connection diagrams for both the transmitter and receiver.

Open the rc-switch “ReceiveDemo_Advanced” example sketch. Hold your remote near your receiver module and press a button. Protocole Somfy (Reverse engi RTS) - Page 3. Bonsoir, Comme promis ci-dessous mon code.Quelques commentaires, à moitié en français... et à moitié en anglais...La classe CCodecSomfyRTS se charge du décodage et de l'encodage. Décodage:=> appeler la méthode "pulse()" à chaque changement d'état (front montant / descendant) avec durée du pulse. La méthode se charge du décodage Manchester et stocke les données au fil de l'eau. Quand toute la trame a été reçue, appel à la méthode interne "decode()". Cette méthode décode la trame reçue, la vérifie (checksum) et affiche sur la console le message décodé (adresse, rolling code, touche pressée).

Emission:=> appeler la méthode "transmit()" avec en paramètre le code de la touche à simuler ainsi que le rolling code courant.NB 1: adresse actuellement en dur dans le code, à positionner manuellement (data[4] à data [6]).NB 2: on se substitue à une vraie télécommande et il faut donc incrémenter le rolling code à chaque émission, ce qui contribue à désynchroniser la télécommande... donc prudence.

Électronique | Informatique Niveau: Avancé Jonathan Schemoul Montage avec la Leonardo Partie 1: Réception en 433 MHz Vous avez sans doute entendu parler ou vu des détecteurs de fumée, d'ouverture de porte, des télécommandes, des prises murales, etc. sans fil ? Que ce soit les modèles chers que vous trouvez en magasin ou les modèles chinois bon marché, la plupart, s'ils ne sont pas avancés, utilisent la bande de fréquence 433 MHz (n'essayez pas ceux en 315, ils sont illégaux en France).

Certains autres sont en 2.4 ghz, mais nous les laisserons de coté pour l'instant. En ce qui concerne ces capteurs en 433 MHz, il se trouve qu'ils utilisent pour la plupart un protocole très simple, introduit par des circuits intégrés chinois à bas coût, les PT2262 côté émission et les PT2272 côté réception (d'autres plus exotiques comme les SC5262 / SC5272, HX2262 / HX2272, EV1527, RT1527, FP1527 ou encore HS1527 peuvent être trouvés et fonctionneront aussi). Montage détaillé Niveau détecteurs : Récepteur Montage.

Arduino All-In-One Remote. Infrared light has been used quite a lot for many different applications in many fields, one of them is communication, specifically between remotes and domestic devices, what allows us to control them without leaving the comfort of our sofa. The process of communication between an emitter (the remote) and a receiver (the device) starts when the user presses any button of the remote, this device has an oscillator and a preconfigured chip that allow the signal to adopt a square waveform with a frequency of 39kHz, depending on the button pressed, the chip will use a determined signal code. This signal travels through the circuit until it reaches the infrared LED, which transforms it into a series of pulses of invisible light (~940nm). If any sensor it's in it's range those pulses will be transformed into a quadratic wave that will indicate what to do according to the programming of the device.
