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.
Inventor's Kit for Arduino (Old Stock) Replacement: KIT-11227. We've overhauled the SIK Manual with new graphics, revised code and in-depth instruction! Also, the kit includes a red translucent breadboard instead of the clear one which some found visually confusing, and the new and improved baseplate! Description: zOMG! Blinking LEDs Controlling a toy motor Controlling a servo Making (bad) music Responding to buttons Twisting a volume knob Detecting ambient light Reading temperature Controlling big devices Mixing LED colors We believe these to be the building blocks of any electronics project. Note: No soldering required. Note: Because Atmel is moving more and more of their production capacity to surface mount ICs, the DIP packaged ATmega328 is becoming more and more difficult to get. Note: There is an error with CIRC-03. Note: This product is a collaboration with Oomlout. Kit includes: Documentation: Replaces: KIT-10152
Build Your Own GPS Car Tracking System Arduino Shield List Find Open Source Alternatives to commercial software | Open Source Alternative - osalt.com 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.

This kit includes all the pieces needed to complete 11 different circuits, along with a experimenter's guide booklet & breadboard layout sheets. Basically everything you need to be playing within minutes of its arrival. No soldering required! Intel and Arduino Team Up to Launch the Galileo
Can you move over? The 74HC595 8 bit shift register OK, so say you have this crazy cool idea where you need to control a ton of LEDs (I know, I know… LEDs). You looked at the multiplexer article, and that was great, but this idea is so cool, you need individual control of each LED, and turning them on one at a time just won’t do. Well again, we are here to help, and now it’s time to introduce you to the Shift Register. Not just any shift register, the super cheap, incredibly awesome 74HC595 8-bit Shift Register! What does a Shift Register do? Basically a shift register will, in the end, let you expand on the digital outputs you have on your mictrocontroller. But the way it works is a little confusing to think of at first, and these are helpful enough that it is really worth understanding what the heck is going on under the hood. You can imagine a shift register as a row of chairs. Now, every 10 seconds or so, someone rings a bell, and everyone has to get up and move one chair to the right. How does this let me control LEDs again? Code
Pinguy OS 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 !
