Blynk is an app with which you can control any piece of electronics you have build, eg. a circuit build with an Arduino. To get started with Blynk, you can follow the getting started guide: www.blynk.cc/getting-started then continue at step 5 of docs.blynk.cc (under getting started) to add a first Widget. The first example (BlynkBlink) builds … Continue reading Getting started with Blynk
Tomorrow a Littlebits-workshop will be held for students doing a project on “Design for Specific Users”. We are going to practice building small, interactive circuits. Aim is to investigate design possibilities in the idea phase of the design process and quickly try-out different directions for idea’s. Students are encouraged to experiment freely by building circuits, mixing … Continue reading Idea generation with LittleBits for “Design for Specific Users”
On Tuesday December 19th I will give a workshop on Mobile App Development. The slides of my presentation can be found below. The workshop introduces basic concepts of app development, highlights required (programming) skills and introduces common ways apps are build: through hybrid frameworks or native. It also briefly mentions other ways a prototype (of an … Continue reading Mobile App Development, an introduction
A checklist to find out if your portfolio website meets minimum requirements. This is a summary of recommendations given in the lessons of Web Technology. 1. The entire site should have a clear identity which is visible on all pages. A clear identity can be a name or an alias and/or a logo. 2. The … Continue reading What makes a good portfolio website?
To show your processing creation in a webpage (or WordPress post or page*) you can use the example code below. <script src=”https://home.et.utwente.nl/slootenvanf/div/processing.min.js”></script> <canvas data-processing-sources=”/slootenvanf/div/processing-example.pde”></canvas> * in WordPress, simply switch to text-mode to enter HTML-code in a post or page. Please take note of the following: If in Processing you have multiple files, you must combine … Continue reading Include a processing file (.pde) in a webpage
Sound files on the NXT Sound-files on the NXT should be in the .rso format. Use wav2rso.exe to convert .wav files to .rso format. .rso files should be copied to the folder C:\Program Files (x86)\LEGO Software\LEGO MINDSTORMS NXT\engine\Sounds before they can be used in the NXT software. Create a “Sound” block, select “Sound File” at … Continue reading Using sound on the NXT
Monday I give a Littlebits-workshop for students doing a project on “Design for Specific Users”. We are going to practice building small, interactive circuits. Aim is to investigate design possibilities in the idea phase of the design process and quickly try-out different directions for idea’s. Students are encouraged to experiment freely by building circuits, mixing inputs … Continue reading Workshop Idea Generation with LittleBits
By utilizing the Arduino-bit and the Proto-bit, all kinds of electronic circuits and components can be connected to a Littlebits circuit. In this example, we connect an Ultrasonic sensor to the Arduino-bit with the Proto-bit. The distance measured by the Ultrasonic sensor will be displayed on the Number-bit. This example is based on the Bat … Continue reading Build a distance-sensor with LittleBits
Sometimes I get a question from a student or colleague on why we choose Java as our base for the introduction to programming classes. Here are some quick reasons: It is a ‘proven’ language to quickly learn programming It is used as first learned programming language in a lot of other universities and high schools It … Continue reading Why learn programming with Java?
Tomorrow I give a Littlebits-workshop for students following the course “Embodied interaction”. We are going to build small, sensory action-reaction type of circuits which are worn by the participants. Aim is that every participant has an output and an input-circuit on his/her body. While walking around, the circuits may trigger reactions on the other participants output circuits. … Continue reading Embodied interaction with LittleBits
