Create a stand-alone Java App that displays info from a connected sensor

This article assumes you have already some experience in creating Java Apps. For instance if you have done the first 2 lectures of the course Application Development. You should also have prepared the DHT temperature/humidity sensor and have a working sketch for it (eg. by completing step 1 and 2 of this assignment, or via … Continue reading Create a stand-alone Java App that displays info from a connected sensor

How to create an App mockup with Figma – a tutorial

A new tutorial is available which introduces steps to create an App mockup using Figma. Figma is an online prototyping tool which can be used to design Apps and websites. This tutorial introduces the basics of prototyping an app with Figma. It quickly ‘touches’ all necessary steps without going into too much detail.¬† You can … Continue reading How to create an App mockup with Figma – a tutorial

Control an RGB LED from an Android App via Bluetooth

In this example we will control a RGB LED from an Android App via a Bluetooth connection. A HM10 BLE Bluetooth module is connected to an Arduino Uno. This tutorial assumes you already have some experience with Arduino. If not, you might want to follow a basic tutorial and/or install the Arduino software (the IDE). … Continue reading Control an RGB LED from an Android App via Bluetooth

Build an App with App Inventor which can display values of a connected sensor

This tutorial describes how to Use App Inventor to build an App which can read the online values of a connected sensor. For this, it uses a WebViewer Component and a Clock to refresh values. This is part 2 of a series, the first part, “Create a connected sensor” can be found here. This second … Continue reading Build an App with App Inventor which can display values of a connected sensor

Getting started with the ESP32 Wifi module

The ESP32 Wifi module can replace an Arduino, as it has similar properties. It’s main advantage is that it is faster, has more memory and has WiFi and Bluetooth on board. Just like the Arduino Nano it can be mounted on a breadboard. This allows building very compact prototype circuits: Make module ready for use … Continue reading Getting started with the ESP32 Wifi module

Connect an ESP8266 module to an Arduino Nano and control it with Blynk

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 (step 1). This example uses an Arduino Nano, of course you may use an other type of Arduino, eg. the Uno. In the second … Continue reading Connect an ESP8266 module to an Arduino Nano and control it with Blynk

Getting started 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
