AutoArduino Lets You Control Your Arduino Projects From Tasker. How Accurate Is Microstepping Really? Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines.

How Accurate Is Microstepping Really?

Most stepper motors you’ll encounter in DIY projects, 3D printers, and small CNC machines are bi-polar, 2-phase hybrid stepper motors, either with 200 or — in the high-res variant — with 400 steps per revolution. This results in a step angle of 1.8 °, respectively 0.9 °. In a way, steps are the pixels of motion, and oftentimes, the given, physical resolution isn’t enough. Hard-switching a stepper motor’s coils in full-step mode (wave-drive) causes the motor to jump from one step position to the next, resulting in overshoot, torque ripple, and vibrations. Also, we want to increase the resolution of a stepper motor for more accurate positioning. On the one hand, microsteps are really steps that a stepper motor can physically execute, even under load. Microstepping So, does this theory apply? Test Setup. Filtering Noisy Data with an Arduino. One of the first frustrating situations a beginning microcontroller programmer will come across is the issue of debouncing switches.

Filtering Noisy Data with an Arduino

Microcontrollers are faster than switches, and the switch has yet to be built that can change state in zero time like they can on paper. This hurdle is easily overcome, but soon we are all faced with another issue: filtering noise from an analog signal. Luckily [Paul Martinsen] has put together a primer of three different ways to use an Arduino to filter signals.

The first (and fastest, simplest, etc.) way to filter an analog signal is to sample a bunch of times and then average all of the samples together. This will eliminate most outliers and chatter without losing much of the information. How to Make a Joystick-Controlled Laser With an Arduino. CameraShutter - Arduino Project Hub.

Definitely not yet, which means if you want your very own IoT power strip — you’ll have to make your own. Good thing it’s not that hard! [Dev-Lab] came up with this project which allows him to control several outlets with his phone. What we really like about it is that he designed a 3D printed housing that fits on the end of the power-strip. This keeps all messy wires out of sight, and it looks like it was designed to be there! Top 10 Kickass Arduino Projects. This app lets you draw digital connections between physical objects. Whether we like it or not, more and more of the world's objects are coming online.

This app lets you draw digital connections between physical objects

Wi-Fi, Bluetooth, and NFC standards are all being used make everything from your car to your smoke alarm digitally connected. The problem is, how do we control and understand what all these objects can do? A group of researchers from MIT think they have the answer: an augmented reality app that lets you see and draw connections between real-life objects. You just point your phone's camera at, say, your lamp or your radio, and its digital controls appear onscreen for you to manipulate.

Introduction to Neural Networks

Arduino Neural Network. A Neural Network for Arduino This article presents an artificial neural network developed for an Arduino Uno microcontroller board.

Arduino Neural Network

The network described here is a feed-forward backpropagation network, which is perhaps the most common type. It is considered a good, general purpose network for either supervised or unsupervised learning. The code for the project is provided as an Arduino sketch. It is plug and play - you can upload it to an Uno and run it, and there is a section of configuration information that can be used to quickly build and train a customized network. The sketch is available for download by clicking here: ArduinoANN.zip. This robotic finger will really push your buttons. Connecting analog devices to the Internet of Things can be a hassle.

This robotic finger will really push your buttons

If your stereo doesn't have Wi-Fi or Bluetooth connectivity, then how will you tell it to start automatically playing your sweet jams when you get home after work? The answer might be a robotic finger called the Microbot Push: a low-energy Bluetooth device that can be stuck to any surface and that physically pushes buttons when you wirelessly tell it to. Low-Cost, Arduino-Compatible Drawing Robot. Bringing women into technical education at times seems to be an insurmountable challenge. As a counter, a small drawing robot created by [MakersBox] might help. The robot was used in a ChickTech workshop for teen girls. The goals for the robot were to have an easy to build, easy to program robot that did something interesting, and was also low-cost so the workshop participants could take it home and continue to learn. These requirements led [MakersBox] to the Adafruit Pro Trinket 3V, stepper motors for accuracy, and a 3d printed chassis to allow for customization.

Another version of the Arduino should work without any problems and even possibly a Raspberry Pi, suggests [MakersBox]. AS-289R2 Thermal Printer Shield.

Oct 2, 2015 | By Kira. Embed with Elliot: Interrupts, the Ugly.

Welcome to part three of “Interrupts: The Good, the Bad, and the Ugly”. We’ve already professed our love for interrupts, showing how they are useful for solving multiple common microcontroller tasks with aplomb. That was surely Good. And then we dipped into some of the scheduling and priority problems that can crop up, especially if your interrupt service routines (ISRs) run for too long, or do more than they should. That was Bad, but we can combat those problems by writing lightweight ISRs. This installment, for better or worse, uncovers our least favorite side effect of running interrupts on a small microcontroller, and that is that your assumptions about what your code is doing can be wrong, and sometimes with disastrous consequences. IFTTT Adds new Maker Channel. The most online popular service for connecting online services together and automating tasks using them, IFTTT, or “If This Then That,” just got hooks into maker-hacked hardware.

Pwm-mosfet-schaltung so richtig? How To Build a Pocket-Sized mBed Signal Generator. Last month, I talked about how to get started with mBed and ARM processors using a very inexpensive development board.

I wanted to revisit mBed, though, and show something with a little more substance. In particular, I often have a need for a simple and portable waveform generator. It doesn’t have to be too fancy or meet the same specs as some of the lab gear I have, but it should be easy to carry, power off USB, and work by itself when required. My requirements mean I needed a slightly more capable board. In particular, I picked up a K64F board. Tiny Headless Servers Everywhere.
