RotaryEncoders. ALPS STEC12E07 Encoder A rotary or "shaft" encoder is an angular measuring device.

RotaryEncoders

It is used to precisely measure rotation of motors or to create wheel controllers (knobs) that can turn infinitely (with no end stop like a potentiometer has). Some of them are also equipped with a pushbutton when you press on the axis (like the ones used for navigation on many music controllers). They come in all kinds of resolutions, from maybe 16 to at least 1024 steps per revolution, and cost from 2 to maybe 200 EUR. I've written a little sketch to read a rotary controller and send its readout via RS232.

It simply updates a counter (encoder0Pos) every time the encoder turns by one step, and sends it via serial to the PC. This works fine with an ALPS STEC12E08 encoder which has 24 steps per turn. I learned about how to read the encoder from the file encoder.h included in the Arduino distribution as part of the AVRLib. Example 1 Oh, a few notes: Interrupt Example Below is some code that uses an interrupt. Think Labyrinth: Maze Algorithms. Maze Classification Mazes in general (and hence algorithms to create Mazes) can be organized along seven different classifications.

Think Labyrinth: Maze Algorithms

These are: Dimension, Hyperdimension, Topology, Tessellation, Routing, Texture, and Focus. A Maze can take one item from each of the classes in any combination. Flood fill Algorithm - how to implement fill() in paint? Use Arduino with TIP120 transistor to control motors and high power devices - All. Hello again.

Use Arduino with TIP120 transistor to control motors and high power devices - All

So you have a DC motor or lamp but no matter how you connect them to your Arduino they just won't work? Guess what, the Arduino is a brain that comes with small muscles. It can control LEDs and other low power nicknacks but not those power motors or lights you need for your next project. The Arduino is good at thinking but not for heavy lifting. Lazy lad. How to Use IR LED and Photodiode with Arduino. In this post I am going to show you how to use and program IR LED and Photodiode pair with Arduino to detect obstacles in a short range.

How to Use IR LED and Photodiode with Arduino

Before going to do the project let us have a brief look at the IR LED and Photodiode. Photodiode is a light sensitive semi-conductor diode which converts the light energy into voltage or current based on the mode of operation. In general Photodiodes are operated in reverse bias condition. C++ How To Convert Ascii To Intergers - C And C++ Setting up an Arduino on a breadboard. Overview This tutorial shows you how to build an Arduino compatible breadboard with an Atmel Atmega8/168/328 AVR microcontroller and FTDI FT232 breakout board from SparkFun.

Arduino Breadboard - DC Optimum Electronics & TechnologiesDC Optimum Electronics & Technologies. How to make your own Arduino board - 13. If your are like me which I am guessing you are, then ever since you got into doing stuff with arduino you have wanted to make your own arduino board.

How to make your own Arduino board - 13

You may be surprised to find out that making the prototyping board is actually very easy, and can have several advantages over using the commercially sold board. For one thing, All the components together cost a little over 15 US dollars as opposed to the $30 that the Uno board sells for. second, you may not actually want a board, but may simply want the atmega chip as the heart of the project, like if you are making a synthesizer or even a robot. In that case, you can just attach the hardware necessary to use the chip, and solder to the pins you need to use without needing the board. Another advantage is making shields.

C++ Loop Types. There may be a situation, when you need to execute a block of code several number of times.

C++ Loop Types

In general statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. Programming languages provide various control structures that allow for more complicated execution paths. A loop statement allows us to execute a statement or group of statements multiple times and following is the general from of a loop statement in most of the programming languages: C programming.com - Learn C and C++ Programming - Cprogramming.com. Arduino Laser Tag - Duino Tag : Overview. Overview Key parts of a duino tagger: IR Transmitter system What - Transistor amplifier, high power IR LED and a lens to give a well focused IR beam.

Arduino Laser Tag - Duino Tag : Overview

Why - To give the tagger means of tagging / shooting other players as well as communicating game information. The transmitter amplifies the transmission signal from the arduino and transmits it using an IR LED, lenses are used to make the signal very directional in order to make the guns behave like guns and make long range transmissions possible. Sound What - Peizo Sounder (& mini sound recorder / playback electronics from greetings card) Why - It’s nice to have some audio feedback from the system. Receivers What - Standard IR receiver module and power regulation capacitor Why - So the gun knows when it has been shot. RC Control and Arduino: A Complete Works : RCArduinoFastLib to the rescue? The quadcopter : how to compute the pitch, roll and yaw.

After having introduced here the basics of an aircraft orientation and how to control it, this article is about actually computing the orientation of the quadcopter in space with sensors and with the Arduino.

The quadcopter : how to compute the pitch, roll and yaw

Which sensors to use? 3 axis accelerometer + compass for yaw To get easily the orientation of a non-moving object (pitch and roll), a 3-axis accelerometer (how does it work?) Can be used. For a static object, it gives the value of the gravity field on 3 axes, therefore its direction. This method has been used in a lot of smartphones and gives pretty accurate results, if you are not moving. Another problem of accelerometers is their sensitivity to vibrations. As you can see, using only an accelerometer is not a valid option. Gyroscope The most common used sensor in quadcopter control boards is the gyroscope sensor. The first problem raised is caused by the nature of the sensor. RC Hobby Controllers and Arduino. RC Hobby Controllers and Arduino Skill Level: Intermediate by NPoole | May 22, 2012 | 39 comments Remote Control Arduino Robots, cars, robotcars, and all sorts of prank devices require some degree of remote control.

RC Hobby Controllers and Arduino

Most of the time, it's tempting to implement this yourself using XBee or some other wireless technology. RCArduino Yaw Control - Part 2. How To Read an RC Receiver With A Microcontroller - Part 1. Its a very common question, 'How do I read an RC Receiver with my micro controller' and the answer is often very simple however the simple answer is close to useless in a real world application. The approach outlined in this series of posts has been tested in an RC Race car running at 40+ Kmh at a range of 100 meters.

The approach is reliable, resilient, easy to understand and easy to modify. It has been tested using using 27Mhz AM radio equipment and entry level electronics. Use of better quality electronics and radio equipment will provide improvements in range and signal quality however as the development process has demonstrated, even low end equipment can be interfaced with Arduino for control of an RC Race car. Update 05/11/12 Read multiple RC channels with a smoother, faster library - the background to this and the original sketch before optimisation see - Background Information. Reading PWM Signals From A Remote Control Receiver With Arduino. So you want to create a remote controlled device using an Arduino (Link).

To put an Arduino between your RC receiver and servos, you’re going to need to know how to read PWM signals. Getting your Arduino to read signals from an RC receiver is an easy task if you don’t mind doing it badly. If you want to do it elegantly, it’s slightly more challenging. First we’ll go over some PWM theory. PWM Signals RC receivers output pulse width modulated (PWM) signals on each channel. A 1.5ms PWM signal like this would drive a standard RC servo to its centre point. Reading PWM Signals From A Remote Control Receiver With Arduino. RC Control and Arduino: A Complete Works : Getting To Know Your Radio System. Here is where things may get muddy because of the way I'm approaching and using the radio system. I'm not going to name the channels by what they control and will be using the channel numbers. See the following link for an initial understanding. I decided to go with Mode 3 because it's easier to remember where the channels are mapped on the transmitter.

I didn't have to change any defaults on the transmitter other than mapping channels 5 to 8. Go ahead and map these channels how ever you like and if you only have a 4 channel radio don't worry about it as I don't make great use of the auxiliary channels. IR Homing Beacon? Guide to gyro and accelerometer with Arduino including Kalman filtering. Hallo everybodyI recently bought this analog 6DOF (six degrees of freedom) IMU board ( from watterott.com. It uses three gyros and three accelerometers to calculate angles in three dimensions. I looked a while for some code online and how to connect with them. After many hours of research I succeeded of making af precise measurement of angles in two directions. I decided to write a short guide for fellow electronic enthusiasts. IRremote Library, Send & Receive Infrared Remote Control. IRremote, by Ken Shirriff, allows you to receive or transmit Infrared Remote Control codes.
