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.

Tutorial Series for Arduino: It begins. This video was featured on the Adafruit Blog on 01/06/11 This tutorial was featured on the official Arduino blog on 3/9/2011 This video was featured on the DIYFilm Blog on 03/19/11 Thanks to a generous sponsorship from element14, I’m putting together a tutorial series on using the arduino microcontroller platform! The arduino is a platform that I’ve done several projects with, and I think it is the best possible way for beginners to get acquainted with electronics. This tutorial series will be aimed at beginner users, but I’m hoping to keep it going with some more advanced topics a few episodes into the future. This first episode will get you acquainted with the arduino uno (the current “flagship” arduino), introduce the programming language, and help you get your first program running! You can download the files associated with this episode here:

Using Relays with Arduino – Turning on the Lights Warning!!! This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution. There are many books and websites about electrical safety procedures and if you’re not sure how to be safe you should read that information. The most basic advice I can give is always assume any exposed wires are live and touching them will hurt a lot at best and kill at worst. 200+ Arduino Projects List For Final Year Students Arduino is a single-board microcontroller. It is intended to make the application of interactive objects or environments more accessible. The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM.

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. Usually I get my first coffee after that, but because I love coffee so much I thought there must be a faster way to get my system updated and running. That's why I build the "Maven Box".

The Internet of Things leads to yet another Growduino We are on the verge of the Internet of Things, where simple devices can now automatically and intelligently trigger an action in the real physical world. It’s going to be a pretty neat transition, as big as the invention of the computer mainframe in the 50's, the PC 30 years ago, and the opening of the Internet to the general public in the 90’s. How big is that? Well to start with, the Gartner Group estimates that 20% of the Internet’s non-video traffic will be sensor data. Oh , and that is only by 2012. But the report also states that it’s a lot like trying to predict the market for plastics in the 1940’s.

Growduino smart garden I've been toying with so many ideas of things to automate, but with the long days and an approaching 2-week trip and two young plants at home, I started working in earnest on a garden control project last night. "Growduino" seemed like the obvious name... ;D This is the simplest possible version-- just an automated watering system, with the nutrient solution pumped up from a reservoir in the tub with a submersible pump. Here's a shot on Flickr: from the description: Arduino and Python For a project (check out my blog for updates) I'm working on I needed to be able to communicate with my arduino, luckily the arduino can communicate though serial. It turns out almost any programming language can be used for serial communication but python seems to be the easiest so far. I had some problems getting it all to work and finding a basic tutorial online proved very difficult. So hopefully this guide will explain the basics to anyone that is looking to start using the serial functions that the arduino provides. I'm going to assume that if you're reading this you have some knowledge of how an arduino works and how to upload sketches and what not, however I will explain the arduino code when we get there. The python code is very basic but I will do my best to explain it as well.

DIY Arduino Battery Capacity Tester - V1.0 [ Play Video ] I have salvaged so many old lap-top batteries ( 18650 ) to reuse them in my solar projects.It is very difficult to identify the good cells in battery pack.Earlier in one of my Power Bank Instructable I have told, how to identify good cells by measuring their voltages, but this method is not at all reliable.So I really wanted a way to measure each cell exact capacity instead of their voltages. Few week ago, I have started the project from the basics.This version is really simple one,which is based on Ohms Law.The accuracy of the tester won’t be 100% perfect, but it does give reasonable results that can be used and compared with other battery, so you can easily identify good cells in a old battery pack. During my work I realised, their are lot of things which can be improved.In future I will try to implement those things.
