The ESP32 Wifi module can replace an Arduino, as it has similar properties. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: To get started, Sparkfun’s “ESP32 Thing Hookup Guide” is a good tutorial. I am not going to repeat that. If you want a … Continue reading Getting started with the ESP32 Wifi module
We are going to build a circuit that is connected to an app build with Blynk. For this we connect an Arduino to an ESP8266 module and connect it through Wifi. This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. the Uno. This guide assumes you already have … Continue reading Connect an ESP8266 module to an Arduino Nano and control it with Blynk
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
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

This example presumes you already have some basic knowledge about Arduino and programming Java applications with Eclipse. If you have an RFID reader module attached to your computer (via a USB serial connection) you can read RFID data from a Java application. For instance, you can use the unique id (Card UID) to identify something or … Continue reading Add RFID identification to a Java application
In this previous article we learned how to build an App with App Inventor and connect it to a Lego Mindstorms NXT. Now we will extend that App to control a Catapult robot. If you have not done so already, first build the Catapult. Now that you are able to connect your phone to the … Continue reading Remote control a catapult with an App build with App Inventor
First steps To be able to use App Inventor, you will have to register with a Google Account. So go to the site ai2.appinventor.mit.edu and register/login. Install the MIT AI2 Companion app on your phone. To be able to identify your NXT (if there are many Bluetooth devices), you might want to change its name: Start the Lego … Continue reading Control a Lego Mindstorms robot with your phone with App Inventor
