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.

Débuter avec Arduino! - Chapter Zero «tronixstuff Hello world! Updated 24/11/2012 Please join with us as we learn about electronics and the Arduino! Together through this series of tutorials I would like to share with you a journey of learning, exploration and fun with the Arduino system, and make some enjoyable, useful, interesting, useless and practical things. These posts will be published on a regular basis, on top of the other non-micro controller posts. Instead of listening to someone talking really quickly on a video, you can read and follow through at your own pace, see examples in action, learn a great deal – and be inspired to make something of your own.

HTML & CSS Crash Course Are you curious about web development but don't know where to start? Would you like to be able to build your own websites? Have you tried learning HTML and CSS, but found other courses too boring or difficult? If your answer is YES to any of these questions, then this is the course for you! Arduino Tutorial: An Introductory Guide Update! Don’t miss our famous article:Â Top 40 Arduino Projects of the Web. Previously we introduced you to the Arduino and it’s awe-inspiring incredibleness.

Bluetooth \ Wiring By Mitchell Page Mpag5967 [at] mail.usyd.edu.au Key Centre of Design Computing and Cognition, University of Sydney , Australia Normally you would use a serial USB cable connected from your computer to your Wiring board for receiving data sent from a computer running processing to your board. This tutorial demonstrates how to execute this same process, but wirelessly using Bluetooth. We will test this by being able to turn an LED on/off wirelessly. You will need to use an adaptor to power your board for this tutorial. This tutorial covers communication from the computer to the board; not from the board to the computer.

The Maven Box: an Arduino Controller for Software Developers - All Every job has it's routine. I am a software developer who works with a Git/Maven based workspace everyday. So when I start working, my daily routine is to update and build my local workspace, pulling changes from GitHub, execute a maven build and execute the updated software.

NRF24L01-2.4GHz-HowTo Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:Remote sensors for temperature, pressure, alarms, much moreRobot control and monitoring from 50 feet to 2000 feet distancesRemote control and monitoring of nearby or neighborhood buildingsAutonomous vehicles of all kinds These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip. (Details) The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The low-power short-range (200 feet or so)Transceiver is available on a board with Arduino interface and built-in Antenna for less than $3! See it here.

CSS3 Tutorial - An Ultimate Guide for Beginners CSS is the key presentational technology that is used in website design. CSS stands for Cascading Style Sheets. CSS is a standard style sheet language used for describing the presentation (i.e. the layout and formatting) of the web pages. Prior to CSS, nearly all of the presentational attributes of HTML documents were contained within the HTML markup (specifically inside the HTML tags); all the font colors, background styles, element alignments, borders and sizes had to be explicitly described within the HTML. As a result, development of the large websites became a long and expensive process, since the style information were repeatedly added to every single page of the website. To solve this problem CSS was introduced in 1996 by the World Wide Web Consortium (W3C), which also maintains its standard.

Arduino Tutorial - Lesson 5 We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch! You're probably familiar with switches, there's tons of them in your house. One kind of switch you use every day is a light switch.
