Speech Synthesizer Synthesized speech was for a long time the Holy Grail of computing, and back in the 1980s when a 4MHz CPU made your computer the fastest machine in the neighborhood it just wasn't practical for software to create intelligible speech. In those days the only sensible way to generate speech was to offload the task to dedicated hardware because the CPU simply couldn't keep up. The most widely used speech chip through the 80s and early 90s was the famous SPO256A-AL2, the allophone speech processor. It was used in toys, in external speech synthesizer peripherals for desktop computers, in industrial control systems, and all sorts of other unexpected places. Then as CPU power continued to increase rapidly speech synthesis was moved to being a software function, and nowadays of course it is almost always done entirely in software by the main CPU using only a tiny fraction of the available processing power.

MP3 and MIDI Codec - VS1053B Description:VS1053b from VLSI is a single-chip Ogg Vorbis/MP3/AAC/WMA/MIDI audio decoder and an IMA ADPCM and user-loadable Ogg Vorbis encoder. It contains a high-performance, proprietary low-power DSP processor core VS DSP4, working data memory, 16 KiB instruction RAMand 0.5+ KiB data RAM for user applications running simultaneously with any built-in decoder, serial control and input data interfaces, upto 8 general purpose I/O pins, an UART, as well as a high-quality variable-sample rate stereo ADC (mic, line, line + mic or 2×line) and stereo DAC, followed by an earphone amplifier and a common voltage buffer. VS1053b receives its input bitstream through a serial input bus, which it listens to as a system slave. The input stream is decoded and passed through a digital volume control to an 18-bit over-sampling, multi-bit, sigma-delta DAC. The decoding is controlled via a serial control bus. Available in a LQFP-48 pin 7x7x1.4mm package. Features: Documents:

Arduino Robot 2 - Wandering Tank What a busy couple of weeks I have had. Many upgrades for the printer have arrived, and work continues on understanding and possibly building Hexy before my Kickstarter version arrives from Arcbotics. In this post I will cover the upgrades I have made to the printer; why I made the upgrades, their cost; and finally show some updated Hexy prints to show off the new accuracy. First; I was printing the Seej Starter Set, in preparation for taking my printer to work on my last day. While doing so, the printer gave up the ghost. Badly. So, because of this complete printer failure and needing to order new parts anyway; I decided to do the upgrades that are suggested to get good accuracy. 2 x Timing Pulley, GT2, 20 Tooth - $11.00 each3 x Timing Belt, GT2 - $9.00 each2 x Motor Shaft Coupling, 5x8mm - $7.00 each. Moving along... So first, the change to the coupler: With the upgrades installed, it's like a new printer!

Top 10 DIY Arduino Projects and HOW-TO Tutorials! Arduino has been widely popular among hackers and DIY-addicts out there for modding/hacking things. For those of you just entering the Arduino world, here’s a bunch of great Arduino tutorials/projects that can help you jump-start your next project. 1) Did you know that you can program/flash your Arduino wirelessly? For those of you who are going to be making devices where the Arduino is hidden from easy access, read up on how you can program your Arduino wirelessly using Xigbee modules over at Lady Ada’s site. 2) Arduinome is a project the Monome for audio sequencers. 3) For energy eco-projects, you can refer to this great site on OpenEnergyMonitor, which uses Arduino and complete details are provided for making your own home energy monitor. 4) DIY Arduino Earthquake Seismic Detector can actually detect earthquakes, perhaps great for any project requiring sensing of vibrations and whatnot. 5) Need some resources on robots using Arduino? 9) The Magic Mirror is one of my all-time favorites.

Answered by Jacket Chueng | 2013-12-27 Was this useful? i need to do a hobby project with rainbowduino v3.0b,i have the board but i don't have the software of that board gave me a solution Hey Navaf . Alex Liu | 2013-11-22 Was this useful? Connect 4 rainbows together Please, can you give me a scheme how to connect 4 Rainbows ? Does anyone know how to scroll a word on this device.

Arduino Tutorial - Learn electronics and microcontrollers using Arduino! So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?" In general, most of these people have seen some of my projects and want to be able to build similar things. Unfortunately, I have never been able to point them to a good site that really takes the reader through a solid introduction to microcontrollers and basic electronics. I designed this tutorial course to accompany the Arduino starter pack sold at the Adafruit webshop. The pack contains all the components you need (minus any tools) for the lessons Follow these lessons for happiness and prosperity. Lesson 0 Pre-flight check...Is your Arduino and computer ready? Here are some recommended tools: If you need to get any soldering done, you may also want.... All of the content in the Arduino Tutorial is CC 2.5 Share-Alike Attrib. Love it? To some extent, the structure of the material borrows from: The impressively good "What's a microcontroller?"

Stop | arduino | matael... vendredi, 19 août 2011 [ arduino ] Comment gérer tout ce qui est nécessaire et réagir aux nouvelles données avec un microcontrôleur ? Dans la programmation d'une application pour microcontrôleur, on ne va pas loin si on doit vérifier en permanence l'état des différentes pins. Certains changement d'état des pins doivent bénéficier d'un traitement rapide, dès leur apparition. Comme je le disais tout de suite, au cours de l'éxécution d'un programme, on peut (en fait, on en a très souvent besoin) de réagir à un changement d'état sur une (ou plusieur) des pins du micro-controleur. Apellées en anglais IRQ (interruption request ou demande d'interruption), les interruptions matérielles sont provoquées par un changement détat sur une des lignes I/O matérielles d'un microcontrôleur. Imaginez que, dans l'attente d'un changement de niveau sur une des pins du microcontrôleur, vous dussiez insérer entre chaque instruction du programme un truc du genre : if (ancien_etat ! Fonctions attachInterrupt() Où : ...
