Triggering a Camera’s Flash with Sound and Light Update: Check out my latest Camera Axe project for a much more robust device that handles this or my store where I sell the Camera Axe. For those just wanting to see the pretty pictures, click here. This article focuses on making the sensors used to trigger a camera’s flash using a microphone or a cheap laser pointer. Since I’ve already described how to do the actual firing of a camera’s flash here I won’t focus on that part of this project today. There are a lot of places on the web that describe how to trigger a flash with an electrical circuit, but I feel that using a microcontroller like Arduino offers big benefits. Arduino Tre Arduino TRE, the first Arduino board manufactured in the U.S. Thanks to the 1-GHz Sitara AM335x processor, Arduino developers get up to 100 times more performance with the Sitara-processor-based TRE than they do on the Arduino Leonardo or Uno. This performance opens the doors to more advanced Linux-powered applications.
Easy Projects to Get Started with Scratch: Drawing 2D Shapes I had my first computer programming experience in ninth grade. I had just moved, and my new guidance counselor persuaded me to take a computer programming class because there were no other open electives. I was dubious. It appeared that coding was either not fun, not cool, not easy, or perhaps all three. Getting Started with ArduBlock DOWNLOAD Ardublock 1.Download ardublock-all.jar ArduBlock 2. In Arduino IDE, open menu “Arduino” -> “Preferences” 3. 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
Guilherme Martins : PAPERduino’s design This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D This is the the first version of the layout design, next we will try more designs, and another materials. You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards. If you do, please share your photos with us, we would love to see them ;)
MacOSX This document explains how to connect your Arduino board to the computer and upload your first sketch. 1 | Get an Arduino board and USB cable In this tutorial, we assume you're using an Arduino Uno, Arduino Duemilanove, Nano, Arduino Mega 2560 , or Diecimila. If you have another board, read the corresponding page in this getting started guide. You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. (For the Arduino Nano, you'll need an A to Mini-B cable instead.)
The Finch Scratch is a tile-based visual programming language, which is an excellent first language for children to learn. We are providing a helper app that allows you to use Scratch 2.0 with Finch and Hummingbird. This is beta software and there are several bugs: please test it and let us know if there are bugs or if you'd like us to make changes to anything. User Guide Video Tutorials Installation Projecte Scratch Features Arduino objects offer blocks for the basic microcontroller functionalities, analog and digital writes and reads, and also for higher level ones. You can find a block to manage Parallax continuous rotation servomotors. Creating Arduino objects is available in 3 different ways as in the Scratch environment.
Projecte Scratch What is Scratch? Scratch is a learning environment developed by the Lifelong Kindergarten Group at MIT Media Lab. It's 100% free software, and aims to provide programming to everyone from 8 years old. Currently is being used worldwide, and experiences with Scratch are everywhere (as was seen in Scratch Day ). Scratch is a learning environment developed by the Lifelong Kindergarten Group at MIT Media Lab. It's 100% free software, and aims to provide programming to everyone from 8 years old. Interrupts, the easy way Many folks starting out in microcontrollers do not know what interrupts are, or are intimidated by them. Today I hope to shed some light on this easy to use, and useful function. There are two ways to detect if an event has happened, polling, and interrupts.
Getting Started - BLE Shield — RedBearLab Important: Blend, Blend Micro and our BLE Shield share the same libraires. If you have followed our other "Getting Started" guide and installed the above libraries, you can skip this section go to "BLE Shield Setup" Check your "Sketchbook location" in Arduino IDE (it is for storing Arduino support files), go to menu File > Preferences... (on Mac OSX, go to menu Arduino > Preferences...) Exit/Quit Arduino IDE Remove older versions of Nordic & RedBearLab Libraries, go to your Sketchbook folder (e.g.
Build Your Own Blocks (Scratch Modification) The BYOB logo. Build Your Own Blocks — often referred to by its acronym, BYOB — is a modification of Scratch, made mainly by the users Jens and bharvey. It includes many features that are not available in Scratch without many large modifications to the source code (see Shift-Click-R for details) — these range from building your own blocks to Mesh. The primary focus for this Scratch modification is first-class data. Features The other BYOB logo.
