Puzzlebox Orbit: Using an Arduino to Control an Infrared Helicopter Here we explain in a very broad sense how an infrared remote control works. There is at least 1 infrared LED (or Infrared Emitter, IR LED, IR Emitter) inside every infrared remote control, including the one you use to control your TV set. When you press a button on the remote, the IR LED will give out a certain series of "LOW"s and "HIGH"s which represents a series of "0"s and "1"s. (To be strict, it is common that a "HIGH" and a corresponding "LOW" consist of a "0", and another combination of "HIGH" and "LOW" with different period represents a "1".) Different series of "0"s and "1"s can mean different things, for example maybe "1100100000111" can mean "Turn Off the TV", and "001101011100" can mean "Volume Down".
Sound / / Piezos diagram: Inside the Piezo Buzzer A Piezo is an electronic device that can be used to play tones and to detect tones. stream] Controlling Arduino with Android using Processing IMPORTANT NOTE: These examples are optimized for Processing version 2.0.3a. Since Processing was heavily rebuilt at version 2.0.6a, these examples are no longer compatible with the latest releases. The good news is that the rebuilt software is significantly easier to work with. The latest official instructions for Processing+Android are available here.
Setting Up App Inventor You can set up App Inventor and start building apps in minutes. The Designer and Blocks Editor run completely in the browser (aka the cloud). To see your app on a device while you build it (also called "Live Testing"), you'll need to follow the steps below. You have three options for setting up live testing while you build apps
10 Breadboard Projects For Beginners Use of arduino in this instructable is prohibited :D Breadboard is a great way to construct electronic projects easily and in less time without the need of soldering. A problem that is faced by beginners in the field of electronics is that they cannot solder the components neatly on printed circuit boards. One bad solder joint can lead to the project not working. When the project does not work, they eventually loose their confidence and cease to continue making projects. Before attempting another project, they have to think twice.
LightScythe - The Mechatronics Guy Battery power is provided from a 6V SLA battery, which is able to power the strip directly without regulation. Parts list (Per scythe): Software: Arduino code: The arduino code is quite simple. The software parses input from the serial port (Xbee) and writes it to the staff. Arduino + Servo + openCV Tutorial [#openFrameworks] by Joshua Noble One of the my favorite things about creativeapplications.net has always been the small tags one can find beneath the name of an application indicating among other things, the technology used to create it. That little nod to the process and to all the work that went into creating the libraries and techniques that an artist or designer uses helps not only contextualize the work but it also helps give recognition to everyone who has contributed their time and expertise to building tools for creative expression in code. Figuring that some of the readers might be interested in learning a little more about these frameworks I’ve put together a quick walk-through of how to connect up two of those tools that one so often sees attached to the names of the projects profiled here: openFrameworks and Arduino. Arduino For this tutorial you’ll need a few things:

IntegerConstants Reference Language | Libraries | Comparison | Changes Integer constants are numbers used directly in a sketch, like 123. By default, these numbers are treated as int's but you can change this with the U and L modifiers (see below). Beginner Arduino The Arduino is a pocket-sized computer (also called a "microcontroller") that you can program and use to control circuits. It interacts with the outside word through sensors, leds, motors, speakers... even the internet; this makes it a flexible platform for lots of creative projects. Some popular uses include: - programmable light displays that respond to music or human interaction - robots that use information from sensors to navigate or perform other tasks - unique, customizable controllers and interfaces for music, gaming, and more - connecting real world objects to the internet (twitter is especially popular) - anything interactive - automating and prototyping
Arduino-controlled RGB LED Infinity Mirror Update 11/22/2013: Thanks to everyone who voted for this project in the Microcontroller Contest! It was one of three first-prize winners. Update 9/17/2013: Thanks to everyone who voted for this project in the Arduino contest (I was one of ten "second prize" winners)! If you want to try this project with an addressable LED strip instead of an analog strip, check out the Rainbow Jar project (also an Arduino contest winner). Monochrome OLED Breakouts This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
Siliconfish: Arduino LCD Countdown Clock Quickie project for a desktop clock that counts down to when my work project has to be done, then counts how many weeks it is late. The design is the "raw electronics" look. The arduino is mounted on the back of the large LCD display by nothing more than a stacked header, and hot glued to a small piece of wood for a base. The code is built on top of the basic example for a clock that syncs from the PC, found here: The Arduino Time Library on the Arduino When plugged into the PC and using the Arduino serial monitor, it waits for you to enter a unix timestamp.
Mert Arduino: Arduino Tutorial 05 - Stepper Motor Control with Motor Shield Stepper motors are great for semi-precise control, perfect for many robot and CNC projects. This motor shield supports up to 2 stepper motors. The library works identically for bi-polar and uni-polar motors For unipolar motors: to connect up the stepper, first figure out which pins connected to which coil, and which pins are the center taps. If its a 5-wire motor then there will be 1 that is the center tap for both coils.
