Brancher et programmer un encodeur rotatif. Un encodeur rotatif est semblable à un potentiomètre sauf qu'il continue à tourner à l'infini, dans les deux sens.

Brancher et programmer un encodeur rotatif

Je vais essayer d'expliquer son fonctionnement avant d'attaquer son branchement et le code qui va avec. Fonctionnement A mon avis, la première chose à savoir c'est que votre encodeur ne donne pas une position absolue (comme le potentiomètre) mais une position relative, par rapport à la position précédente. Il faut alors que votre microcontrôleur stocke cette valeur dans une mémoire si vous souhaitez la récupérer à chaque démarrage.

L'encodeur qu'on va utiliser possède 3 broches : une pour la masse, les deux autres vont générer chacune un signal carré. Un signal carré est un signal qui prend uniquement deux valeurs : HIGH quand il vaut 5V et LOW quand il vaut 0V. Pour faire simple, il suffit de lire l'état des 2 broches. DIY Muscle Sensor / EMG Circuit for a Microcontroller. Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders.

DIY Muscle Sensor / EMG Circuit for a Microcontroller

However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG systems remain expensive and mostly outside the grasp of modern hobbyist. This instructable will teach you how to make your own muscle sensor / EMG circuit to incorporate into your next project. Use it to control video games, robot arms, exoskeletons, etc. Click on the video below for a demonstrations on how to hook up and use your EMG circuit board!

Vous savez donc que le logiciel qui vient avec l’Arduino appelle une fois la fonction setup() puis appelle ensuite loop() de manière répétitive. Généralement, pour mettre en œuvre un système, on va, dans loop(), lire des entrées de l’Arduino, qu’elles soient analogiques ou numériques, exécuter un certain nombre de calculs en fonction de ces entrées puis modifier l’état du système, ce qui aboutira éventuellement à positionner des sorties.

Ces lectures se font donc de manière répétitive. KTechlab. Launchpad / Sequencer with MIDI output - All. Gizmo. Gizmo is the codename for an open source MIDI utility device which targets the Arduino Uno or Mega.


It can do at least this: There will be yet more things coming for the platform. Demos Gizmo's LED display is rock-solid, steady bright red. But in these videos it looks like flickery, junky yellow due to the camera. :-( Annoying. Obtaining Gizmo Github Repository Manual (in PDF) To assemble Gizmo, you'll need an Arduino Uno or Mega (if you want to develop, get a Mega), a SparkFun MIDI Shield, some Arduino headers (I use stackable headers), an Adafruit 16x8 LED Matrix Backpack (they come in various colors, shapes, and sizes -- I use 1.2" round amber red), and four Male/Female Jumper wires. Arduino Based MIDI Sequencer. I’ve programmed a sequencer for the Arduino microcontroller platform, designed to be used with the Sparkfun MIDI Shield.

The sequencer combines an arpeggiating sequencer like that found on the Access Virus with a transposable recording sequencer, similar to the one on the Roland SH-101. get it here.

With Raspberry Pi and I2C communication, we can connect the Pi with single or multiple Arduino boards.

Raspberry Pi and Arduino Connected Using I2C - Oscar Liang

The Raspberry Pi has only 8 GPIO’s, so it would be really useful to have additional Inputs and outputs by combining the Raspberry Pi and Arduino. There are many ways of Linking them such as using USB cable and Serial Connection. Why do we choose to use I2C? One reason could be it does not use your serial, USB on the Pi. Given the fact that there are only 2 USB ports, this is definitely a big advantage. In this article I will describe how to configure the devices and setup Raspberry Pi as master and Arduino as slave for I2C communication. Multiplexage d’ADC sur Arduino.

Maximising your Arduino's I/O ports with MCP23017

By John Boxall – a series of articles on the Arduino universe. The first chapter is here, the complete series is detailed here. [Updated 04/12/2014] In this article we discuss how to use the Microchip MCP23017 16-bit serial expander with I2C serial interface. This 28-pin IC offers sixteen inputs or outputs – and up to eight of the ICs can be used on one I2C bus… offering a maximum of 128 extra I/O ports. Here is our subject of the article in DIP form: At this point you should also download yourself a copy of data sheet – it will be referred to several times, and very useful for reference and further reading.

First, let’s look at the hardware basics of this IC. The sixteen I/O ports are separated into two ‘ports’ – A (on the right) and B (on the left. Stp_596. An Interface with a STP16C596 16-bit Constant Current LED Sink Driver copyright, Peter H Anderson, Baltimore, MD, Jan ,'08 Introduction.

This version is an update to version 2.2. Angle was removed from servo config. Otherwise, the protocol itself has not changed since v2.2 but the Arduino Leonardo was added to boards.h and additional features such as I2C were implemented in the StandardFirmata example application. You can see a history of the changes on the ProtocolChangeLog page. The Firmata protocol is designed to be extended, the Proposals page is the place to propose new extensions.

SerialLCD. Serial LCD tutorial by djmatic With a simple four wire connection and the code below, the Arduino can drive serial LCD displays. The main advantage of serial LCD's is that they are easier to wire up, since the Arduino talks to the LCD over a single pair of wires. SerialLCD. Libraries. Reference Language | Libraries | Comparison | Changes The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data.

To use a library in a sketch, select it from Sketch > Import Library. A number of libraries come installed with the IDE, but you can also download or create your own.

Favorited Favorite 1 Introduction. How to build a MIDI controller with the Arduino, Firmata and Pure Data. Time to start contributing some knowledge back to the wonderful world that is the internet; today, a step by step nice and easy tutorial on getting started to building your own MIDI controllers with the arduino. When researching for my ableton controller project, I didn’t find much out there about using firmata on an arduino to send data to software. The standard approach just seemed to be create the code in the arduino language, upload it to your board and hack one of those MIDI to USB cables as a bodge job way of getting the MIDI out of the arduino.

Some ATtiny chips do not have direct support for hardware based serial and therefore the Serial object is unavailable in your code, however, it is easy to add a SoftwareSerial object and view output in the Arduino IDE. The code in this article uses an ATtiny85 with an FTDI Serial TTL-232 USB Cable to send or receive information. A USB Serial TTL Cable can also be used since the CTR and RTS pins are not needed.

MPR121 Hookup Guide. DFUProgramming8U2. The ATmega16U2 chip on your Arduino board acts as a bridge between the computer's USB port and the main processor's serial port. Previous versions of the Uno and Mega2560 had an Atmega8U2. It runs software called firmware (so named because you couldn't change it once it had been programmed in the chip) that can be updated through a special USB protocol called DFU (Device Firmware Update). Here's how to update the firmware on your 16u2 in a few steps. Check whether you need to update the firmware. HIDUINO via DFU Method · ddiakopoulos/hiduino Wiki. OpenTransport.
