Touch screen become more and more popular.
The SphereBot can plot images on spherical objects like table tennis balls, golf balls, eggs etc. It is inspired by the original EggBot by EvilMadScientist , but built from 2 old stepper motors and some steel rods (all cannibalized from old flatbed scanners), some MDF and plywood and a few 3d printed parts (printed with my MakerBot Cupcake). The electronics are simply an Arduino and two Polulu A4983 stepper motor drivers (on the bread board).
From ShivalWolf Android App Inventor Wiki So this project was to demo connecting an Android Phone to an Arduino via Bluetooth.
Introduction This article provides the necessary steps in allowing your Arduino board to be interfaced to the web using novel but Open Source technologies everyone can use. This has long been available but using other alternative ways of doing things by using LAN, or Zigbee modules/shields for Arduino, and they can be quite expensive. However, depending on the purpose, this simple solution may be sufficient enough.
The giCentre is engaged in high quality research and education into the role and design of graphical techniques for exploring and analysing data and disseminating information. We have particular expertise in geographical and temporal information. We develop the theory, practice and technology that supports information visualisation, visual analytics and Geographical Information Science (GIS), offer innovative and high quality learning opportunities and play a leading role in the international geographical information and visualisation community. You can find out more about our research and publications . Please get in touch if you want to find out more. giCentre at Geoviz Hamburg Jason, Jo, Aidan, Alex, Iain and Roger participated in GeoViz Hamburg , a workshop characterised by short focussed presentations, demos and plenty of discussion time.
gwoptics A library by Daniel Brown and Andreas Freise for the programming environment processing . Last update, 17.03.2010. This library provides a set of tools for drawing graphs in 2D or 3D.
What is the timeline? The timeline is a combination tool and library designed for Processing . It lets you draw variables. The timeline tool is a graphical tool for the Processing Development Environment that allows you to draw curves representing variables over time. The timeline library allows you to use these variables in your sketches. The timeline tool looks like a traditional timeline that you might see in multimedia applications like Flash, Reason, Final Cut Pro, etc.
This article introduces an implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5DOF IMU unit from GadgetGangster – Acc_Gyro . The theory behind this algorithm was first introduced in my Imu Guide article .
ConfigurationFileSyntax - serialchart - Seria Chart - Analyse and chart serial data from RS-232 COM ports#Describes Configuration file syntax for SerialChart application (.scc files) SerialChart configuration is done through a text file. The general format of the file is as follows: [ section1 ] param1 = value param2 = value ... [ section2 ] param1 = value param2 = value Each configuration file starts with the [_setup_] section, here you can setup global parameters.
In the video at above we show the BlueZigbee example, which is based on Eridani ( available for purchase here ). To get BlueScripts go to the Android Market. BlueScripts is a program for the scripting of Bluetooth ASCII messages to Bluetooth radios via an Android phone and an XML file.
In this post I will be talking about how to get an Arduino and an Android tablet talking to each other using Bluetooth We will be using an Arduino Uno ($29.95) with a Silver Bluetooth Mate ($40.95) from SparkFun.com , and my Samsung Galaxy 7.0 running Android 2.3.4. Wiring the bluetooth mate to the Arduino is really simple and spark fun has a great link on the product page explaining it.
A Library to Ease Accessing Flash-based (PROGMEM) Data Note: Flash 4.0 now supports Arduino 1.0! Storing static program data in flash/PROGMEM is a tricky part of Arduino programming. To save precious RAM, a novice user already at odds with unfamiliar C++ syntax must digest such daunting concepts as prog_char, PSTR(), PROGMEM, pgm_read_word(), etc. Even seasoned users get tripped up by the indirection and typecasting that are required to retrieve valid PROGMEM data.
Here you will learn to build your own Pachube/Arduino/Processing application step-by-step, connecting Arduino to Processing to Pachube. This tutorial consists of two basic steps. Use Arduino to create an input to Pachube (i.e. provide Arduino's realtime sensor readings for others to connect to). Use an output from Pachube to control Arduino (i.e. to have your Arduino respond to realtime sensor readings from remote devices). These tutorials assume that you are using Arduino 12 and Processing 1.0.1 , with an Arduino NG or Diecimila device. The tutorials also work with earlier versions of Processing (tested to v0135) and Arduino, though you will need to download Firmata manually, and check baud rate depending on which version of Firmata you choose.
The DS1307 is a classic staple of DIY clocks. http://www.maxim-ic.com/datasheet/index.mvp/id/2688 Read the datasheet, it contains the commands for the chip and other details. You'll need to know this stuff when you look at my source code so you know what's going on. What does it do?
