How to build an arduino energy monitor Including voltage measurement via AC-AC voltage adapter and current measurement via a CT sensor. This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home. It measures voltage with an AC to AC power adapter and current with a clip on CT sensor, making the setup quite safe as no high voltage work is needed. The energy monitor can calculate real power, apparent power, power factor, rms voltage, rms current. All the calculations are done in the digital domain on an Arduino. Step One – Gather Components You will need: 1x Arduino Voltage sensing electronics: 1x 9V AC-AC Power Adapter 1x 100kOhm resistor for step down voltage divider. 1x 10kOhm resistor for step down voltage divider. 2x 470kOhm (for voltage divider, any matching value resistor pair down to 10K) 1x 10uF capacitor Current sensing electronics 1x CT sensor SCT-013-000 1x Burden resistor 18 Ohms if supply voltage is 3.3V or 33 Ohms if supply voltage is 5V.
4 Operating Systems for the Arduino I was working in the lab, late one night, when my eyes behold an eerie sight... Yes, Halloween is a long time ago, but that stupid song is still stuck in my head. I miss Halloween. I never got to post up pictures of my skeleton running off IXM's. :-)Anyway, I was browsing the Arduino forums and saw this cool post about DuinOS, a real-time embedded "operating system" for the Arduino. DuinOS by RobotGroupIt's a simple little realtime OS (RTOS) built by the guys at RobotGroup (hello!), and can be downloaded here. Well, that's something of a stretch, but it's getting there... we won't get into context switching an RAM page swapping just yet :-) So then that got me thinking, why not write up the other "OS's" out there for the Arduino platform. Pyxis OS by ArduinoWillThis is a graphical OS built on top of the Arduino and TouchShield platform, and is written by ArduinoWill (aka Thom). Ok. And it's all zipped up over at the Open Source App Store here. I wish I still had screen shots...
Build Your Own GPS Car Tracking System Voice Activated Arduino (Bluetooth + Android) Control your Arduino with voice commands using an Android smartphone! Before we make a voice activated home automation system, we must first learn the basic principles of the experiment. This guide will let you command the Arduino using your Android smartphone and a HC-05 Bluetooth module. The designer of the app did not include a sample code. I looked for alternatives in Google's PlayStore but none was as good as the app that I've found. Luckily, I was able to figure it out although it took me a while to program it. How Does It Work? Home Automation System (on July 4, 2014): A month from now/ I'll be releasing a highly sophisticated home automation + security system. Here's A Quick Video Demo:
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.
Intel and Arduino Team Up to Launch the Galileo Arduino vs Raspberry Pi: Which Is The Mini Computer For You? You’re looking for a small computer to power a laser turret that can shoot multi-coloured balloons – it’s a common situation we all find ourselves in at one point or another – and you’ve heard good things about both Arduino and Raspberry Pi. But you can’t decide – which the best mini-computer for your project? Which is going to prevail as the most useful once you’ve disassembled the turret thanks to that incident with the neighbour’s cat? Which could you play movies on? Don’t worry, James is here to explain all! What’s The Difference? The Arduino and Raspberry Pi may look quite similar – they’re both cute little circuit boards with some chips and pins on them – but they are in fact very different devices. Although the Arduino can be programmed with small C-like applications, it cannot run a full scale “operating system” and certainly won’t be replacing your media center anytime soon. Strengths & Weaknesses So is the Arduino useless then? None So, you’re decided? WAIT!
Fabriquer une éolienne pour moins de 40 € ? | Energethique C’est le défi qu’a relevé Max Robson, jeune étudiant de 22 ans. Son projet avait pour but de créer une éolienne vraiment pas chère avec des éléments de récupération. Cette éolienne pas chère est destinée selon lui à être utilisée dans les pays en voie de développement. Une éolienne DIY qui lui aura couté 20£, actuellement équivalent de 23€ et pas mal de pièces de récup, le petit alternateur d’une Vespa par exemple ou encore une batterie de vieille Ford Fiesta… Ce qui élève certainement déjà un peu le coût du tout et surtout il faut avoir les éléments à disposition, peut-être pas toujours le cas dans les pays en voie de développement auxquels il destine sa création. La petite bête développe une puissance de 11,3 W, ce n’est pas énorme mais c’est déjà ça de pris ! L’article complet du Daily Mail Be Sociable, Share! Parle de ce post à tes amis !
Build a Mailbox Alarm that Sends You a Text Whenever You Get Mail An Arduino With Better Speech Recognition Than Siri | Hackaday The lowly Arduino, an 8-bit AVR microcontroller with a pitiful amount of RAM, terribly small Flash storage space, and effectively no peripherals to speak of, has better speech recognition capabilities than your Android or iDevice. Eighty percent accuracy, compared to Siri’s sixty.Here’s the video to prove it. This uSpeech library created by [Arjo Chakravarty] uses a Goertzel algorithm to turn input from a microphone connected to one of the Arduino’s analog pins into phonemes. There is one caveat for the uSpeech library: it will only respond to predefined phrases and not normal speech. This isn’t the first time we’ve seen [Arjo]’s uSpeech library, but it is the first time we’ve seen it in action. Video below.
