NCWP (Non-Crappy Wedding Present) Tutorial NCWP (Non-Crappy Wedding Present) Tutorial Skill Level: Beginner by RobertC. | October 29, 2010 | 21 comments Overview: What exactly is the NCWP Scavenger Box anyways? Part of the project was inspired by Mikal Hart's reverse geocache box. I can honestly say I'm thrilled with how everything turned out. Story Behind the NCWP Scavenger Box: Here's how it all went down. Downstairs waiting for her was yet another present. The screen informed her that her wedding ring was inside the metal lock box and her quest was to find the key before our wedding, (which was only 2 days away). The clues were cryptic in nature and all pertained to vacations we took together or events we had experienced together. After several clues that continued in this fashion, I knew I would lose her interest. We already had a trip planned the next morning, and I'd planned all the locations all along the path of our trip. Beforehand, I had mailed out two RFID cards, one to each of our parents. The Hardware: Parts List: Power:
Parts & Kits for Arduino Online, Buy Microcontroller Boards, Electronic Components for Arduino - Welcome - Freetronics 595 Shift Register Simulator | ConductiveResistance For beginners, the 595 series Shift Register isn’t easy to grasp. I’ve written an interactive 595 simulator so you can learn out the 595 works without having to wire one together. Play around with it. See if you can get it to produce the output you expect. I would recommend the most recent versions of Firefox, or Safari “Wait a minute! Picture a box that has a hole on either side. That’s kind of how a shift register works. Try the following: Click the Serial Input Toggle button so that the SER pin goes red (that means it’s “HIGH”)Click on the Clock button (Notice the SRCLK pin goes HIGH)Now look at the Storage Register on the right. Now try those steps again, except press the Latch button after each Clock press. Here are a couple of characters for the 7-segment display to get you started: At least one person was looking for part numbers for 595 shift registers. What’s the difference? If you’re looking for one and aren’t sure where to start, I’d recommend going to SparkFun.
Arduino Tutorial - Getting ready This lesson won't teach any electronics, really. Its more for making sure that everything is setup and ready for the future lessons. It will verify the Arduino is working as intended and that the computer you are using is compatible. For this lesson you will need some stuff! Take your Arduino out of its protective bag. Diecimila Arduino Or like this: NG Arduino If there's anything missing or really wrong, make sure to contact the store you bought it from. OK, now that you are satisfied that your Arduino looks good, put the rubber bumpers on the bottom of the board. Depending on which Arduino and which OS you have there are different instructions Now we are ready for the moment of truth, it's time to plug your Arduino in and power it up. The jumper-setting step is only for Diecimila and OLDER arduinos! You'll want it set as shown in the picture above. Make sure your cable is a A-B cable. Plug the thin end into your computer Plug the square end into your Arduino If not, double check:
Arduino Resources Arduino Resources I really love cheat sheets. In a lot of cases they can take the place of an entire manual. So I was surprised, given its popularity that I couldn’t find a single-page reference for the arduino online. I tried to make a sheet that captured all the things I hit the reference for while programming. Any other things you’d like to see added, send me an email and I’ll stick them on Rev 3! Edit: Thanks to Macca and TBAr for their feedback. Download: PNG PDF Visio —- Gavin

PaperDimmerPCB. Regulador de potencia por triac para microcontrolador (compatible con Arduino) Conceptos preliminares Después de buscar un regulador de potencia para microcontrolador mediante triac, sólo he encontrado controles binarios (encendido/apagado), o mediante circuitos especializados. Es por eso que decidí hacer un control sencillo (sólo tiene 8 niveles de potencia). El circuito se basa en el expuesto en la web (muy buena por cierto). En este circuito sustituimos el potenciómetro de 470k por 3 resistencias fijas en serie que puentearemos según nos convenga. Esto lo hacemos mediante tres optoacopladores que a la vez de aislar la parte del micro de la parte de potencia, puentean las resistencias que están situadas en paralelo con el " foto interruptor bidireccional". NOTA: Este circuito funciona solo con motores de tipo universal (con escobillas), para regular la velocidad de motores de inducción (sin escobillas) es necesario realizar un variador de frecuencia. Características del circuito Descripción Y por el lado de las pistas: 1.
Thingiverse - Digital Designs for Physical Objects Resultados de la búsqueda de arduino Prmero tenemos Centipede un shield bastante bien diseñado que nos da 64 pines de entrada o salida, todo esto gracias al protocolo I2C. Tiene un precio de $17.99 USD y puedes comprarlos aquí. Otro multiplexor para arduino es el Mux shield, tiene capacidad hasta 48 entradas o salidas. Este shield hace uso de multiplexores analogicos lo cual hace posible tener hasta 48 entradas analogicas, una cualidad única. Además de todo esto solo hace uso de 4 pines digitales y 3 analogicos dejando libre los demás para hacer uso normal. Es tuyo por el precio de $21.99 USD aquí. El EZ-Exparder Shield, el más sencillo pero tambien más económico, con una expansión de tan solo 13 pones extra que además solo funcionan como salida y que tienen una corriente de salida limitada.
What is Arduino? Learn About This Open-Source Electronics Platform Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Today we will help you get started by showing you some of the options available and how easy it is to get started. Arduino hardware is an open-source circuit board with a microprocessor and input/output (I/O) pins for communication and controlling physical objects (LED, servos, buttons, etc.). The board will typically be powered via USB or an external power supply which in turn allows it to power other hardware and sensors. Arduino also has an open-source software component which is similar to C++. All of this was designed to be easy to use to let artists and makers freely develop their ideas into real objects. Arduino Variants The Arduino hardware being “open-source” means that you can view schematics of every board available. The image below was created using Fritzing and is the layout for a basic Arduino using a bread board. Arduino Uno Arduino Nano Arduino Lilypad Netduino XBee
