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?
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.
The World Famous Index of Arduino & Freeduino Knowledge Arduino Shield List 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. 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. Now bringing this idea back to the 74HC595: This shift register consists of 8 output pins, which are either high (1) or low (0). Hooking it up
Circuits@Home rh_count Relative Humidity Measurement using the Humirel HS1101 Sensor Arduino, BasicX BX24 and PICAXE-18X copyright, Peter H. Anderson, Baltimore, MD, Nov, '07 (Nov, '07). The discussion has be reworked to also include the Arduino. Introduction This discussion focuses on a relatively simple technique for measuring relative humidity using a sensor. It is desireable to measure temperature as people are usually interested in both the relative humidity and temperature. Advantages of this technique for measuring relative humidity are that it is inexpensive and as the input to the processor is a pulse train as opposed to an analog voltage, the RH measurement circuitry may be located several hundred feet from the processor. I offer a small assembled package, consisting of a HS-1101 sensor, TS555 (SGThompson), 49.9K and 562K one percent resistors for the 555 circuitry, and a separate 10K NTC thermistor for measuring temperature.

Arduino I have finally taken the plunge and released Servo Tools For Maya to the world! Servo Tools For Maya is a Python Plugin that sends rotational values over USB the the Arduino Micro Controller. These values are then converted in to Pulse Width Modulation which is used to control multiple Hobby RC Servo Motors. Applications for the plugin are only limited to your imagination. Current Features Include:- Control up to 4 Servos simultaneously. Hardware Requirements:- USB Cable- Arduino Micro Controller- At least 1 RC hobby servo Software Requirements:- The Scripts and Plugin available from this page- Python (separate from the one that comes with Maya 8.5+)- PySerial Python Module for Serial Communication- Maya 8.5 or Higher (32-bit only)- Latest Arduino Software PLEASE NOTE:I'm still prepping the Documentation in Video Form.
52 Weeks Project Latest arduino projects ideas & topics | NevonProjects Looking for an idea to make your next arduino project? Well this is the best place to find it. From arduino uno to arduino due projects, we have the largest variety of ideas for you. How are these made ? PCB (printed circuit board) development for the arduino project. We then use an arduino programmer board and mount the arduino programmable IC on the board.We then code it using arduino and then burn the IC.The microcontroller is then mounted on the PCB board to get the desired output. Arduino provides a comfortable electronic circuit programming experience for electronics enthusiasts. This page lists the largest variety of arduino projects for students, researchers and arduino enthusiasts. Other Project Categories
