Thinking about it and doing intensive research on the web, I found that there were no tutorials and simple designs, anyone with little or none experience with Arduino, API, JSON, WEB SERVER and a plurality of expertise could enjoy this feature ( IoT ). This publication is simple to send variables sensors to clound ( Ubidots ) in a fast , direct and dynamic way.
Robot Operating System Robot Operating System (ROS) is a software framework for robot software development, (see also Robotics middleware) providing operating system-like functionality on a heterogeneous computer cluster. ROS was originally developed in 2007 under the name switchyard by the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot STAIR[2][3] project. As of 2008, development continues primarily at Willow Garage, a robotics research institute/incubator, with more than twenty institutions collaborating in a federated development model.[4][5] ROS has two basic "sides": The operating system side ros as described above and ros-pkg, a suite of user contributed packages (organized into sets called metapackages) that implement functionality such as simultaneous localization and mapping, planning, perception, simulation etc. Despite the importance of robot reactivity, ROS is not a realtime OS, though it is possible to integrate ROS with realtime code.[6] Applications[edit]
20 Projects To Celebrate Arduino Day In the spirit and celebration of Arduino Day, we’ve compiled a list of some great past projects for your enjoyment. While the Arduino UNO and older Duemilanove are two of the most common Arduino boards, the MEGA and the Yún should not be avoided. The MEGA is much like the UNO, however, it has an expanded number of input and output pins, and is often used to control 3D printers. The Yún is ideal for project where onboard wifi connectivity is a must. Don’t forget that shields –boards that plug directly into the Arduino’s header pins– are a fantastic, rapid way to add functionality to a project.

How to create a time lapse video with Raspberry Pi After installing a Pi camera module and capturing pictures and videos with raspistill and raspivid commands, I wanted to create a time lapse video of the nice scenery that I have in the back of my apartment. For those who don't know what it is, time-lapse video (or often-called time-lapse photography) is a shooting technique where contiguous photo frames of a changing scene are captured for an extended period of time in a much lower rate than a typical video frame rate. When the collected frames are played back in a faster frame rate, it creates a so-called "time-lapsing" effect. You might already have seen stunning looking night-to-day time-lapses or fast moving clouds on TV. In this project, I use the following items to create a case for Raspberry Pi and Picam module before capturing time lapse sequences with them. One used plastic snack container One used SD card plastic wrap Dish washing sponge (remove the green scratchy side and use only the yellow soft side).
Speech Recognition and Synthesis with Arduino In my previous project, I showed how to control a few LEDs using an Arduino board and BitVoicer Server. In this project, I am going to make things a little more complicated. I am also going to synthesize speech using the Arduino DUE digital-to-analog converter (DAC). If you do not have an Arduino DUE, you can use other Arduino boards, but you will need an external DAC and some additional code to operate the DAC (the BVSSpeaker library will not help you with that). In the video below, you can see that I also make the Arduino play a little song and blink the LEDs as if they were piano keys.
How to read RC Channels - The RCArduinoFastLib Background - The problem we are solving. Your Arduino can only do one thing at a time, when one interrupt occurs no others can run until the current one finishes. This can cause problems in RC Projects which use interrupts for three key functions - 1) The Servo Library uses an internal interrupt to generate the servo signals 2) The Interrupts we use to read incoming RC Signals 3) The Arduino interrupt that drives the timing functions millis() and micros() When two of our interrupts are triggered at the same time, one will be held waiting until the first one finishes.
Ideas List your project ideas. This can be helpful for both the novice and the experienced. Navigation Python Multithreaded Programming Running several threads is similar to running several different programs concurrently, but with the following benefits − Multiple threads within a process share the same data space with the main thread and can therefore share information or communicate with each other more easily than if they were separate processes.Threads sometimes called light-weight processes and they do not require much memory overhead; they care cheaper than processes. A thread has a beginning, an execution sequence, and a conclusion. It has an instruction pointer that keeps track of where within its context it is currently running. It can be pre-empted (interrupted)It can temporarily be put on hold (also known as sleeping) while other threads are running - this is called yielding.
Coder Projects Things to make. Stuff to learn. Looking for something to do this weekend? Coder Projects are simple, fun, and sneakily educational things that can all be made with Coder and Rasberry Pi. Enter the house like a Sith Lord My daughter is a huge Star Wars fan (even though she hasn't seen any of the movies yet). Not surprisingly, she was all over it when I asked if she wanted to build a Star Wars themed project. I don't know how many times she has made me play the Imperial March (Darth Vader's theme song) when she is wearing her Darth Vader costume so that she can make a grand entrance into the room. So, we quickly settled on this project idea - automatically detect someone coming home and then trigger the playing of the Imperial March just before the person walks into the house.
