Cloud Engineering: Ship faster with better hardware engineering tools - Upverter Dangerous Prototypes · A new open source hardware project every month tlc5947 with tlc5940 library - daisy, but.. I didn't expect the distance <30 cm to be of issue, but at the same time I'm not sure what I based that expectation on.. I don't have a camera at hand now, but will try and send some images soon - the setup is very basic - 8 plain breakout boards with TLC5947's connected by 150mm FFC cable, no further components apart from one plain LED per board to test. Arduino Mini Pro or Duemilanove. With shielded cable, do you think 50cm (*16 TLC's) would be somehow achievable? I have no idea what kind of shielding this would require, do you have a direction to look in? I hardly dare any more questions, but I'm very curious to controlling the TLC's along the library and explanation at which indicates it should be possible to control the TLC's externally over shiftOut. shiftOut(dataPin, clockPin, msbFirst , data); which the above library uses. Is it possible to control the TLC5947 with Arduino's shiftOut function at all?

AC Light Dimmer - Andrew Jessop March 2006 This project came about because a friend of mine had something similar as a component for his final year electronic engineering project. We decided that we would have a kind of competition to see who could build an AVR based AC light dimmer the quickest. I was interested because I had always wanted to experiment with AC power control, and this was the perfect, simple little project. AC Dimming Theory Explanation to go here. Hardware Software The code for this project was written in BASCOM AVR - a BASIC compiler for the AVR microcontrollers. References Silicon Chip Nuts and Volts Aquaponics – Online Temperature and Humidity This project is a part of the Arduino Data Acquisition and Control System described in the upcoming book Automating Aquaponics with Arduino. You can see a live version of this tutorial here: While this project is designed with aquaponics in mind, it does not require an aquaponic system, making it useful for other projects such as home automation. The included application is, therefore, bare-bones, making it easier to integrate into any other App Engine project. How It Works Every sixty seconds, the Arduino will test its connection to App Engine. On startup, the web browser (client) will create a temperature and humidity gauge with values at zero. Software Versions: 1. 2. 3. 4. 5. Update I removed the dependency on the Timer library – it simply wasn’t needed for this application. The Arduino code has been updated. For whatever reason, the Arduino fails to connect on the third HTMLRequest. Finally, I have the serial output on by default.

| dms Travis Goodspeed's Blog The World Famous Index of Arduino & Freeduino Knowledge Electronics Since my V-USB tutorials became popular, a recurring theme in the comments section have been people who are obviously motivated to try out the tutorial, but due to limited exposure to C language and command-line are either having trouble following my short instructions to compile the example .hex files, or being scared of the command-line, have tried to use AVR Studio instead, and fail. I have to admit that first I was a bit annoyed by these people – why are they trying to follow a challenging project, when they seemingly have no understanding of how command line, makefiles, C compiler and linking process works? Then, comment by comment, I finally realized that not everyone started coding in the nineties where you launched Windows 3.11 mostly to play Solitaire, and biggest thing in coding productivity was 80×50 text mode which allowed you to have 16-color hacking bliss in your Borland Turbo C++ 3.0 IDE (or RHIDE, after DJGPP came around). The first one is really easy.
