Tutorial: Create a gamecontroller for the catch-the-ball game
In this tutorial, we are going to create a gamecontroller which can control the game using movements. By tilting the gamecontroller, you can control the movement of the basket. We will extend the game made in the previous tutorial. Carrying out the assignment Realizing the gamecontroller can be done in 2 ways: Using the MPU-6050 Accelerometer … Continue reading Tutorial: Create a gamecontroller for the catch-the-ball game
Java tutorial: Programming a Catch-the-ball game
In this tutorial, you will make a simple game in which balls are launched, which we then have to catch. The user of the game controls a basket in which the balls must be collected. The aim is to catch as many balls as possible and earn points that way. The basket is located at … Continue reading Java tutorial: Programming a Catch-the-ball game
Tutorial: build a connected temperature sensor
Introduction to Arduino and programming . Practicals which use this tutorial have an introductory presentation (pdf). We will build a temperature sensor in this tutorial and connect it with an App. It uses an DHT11 temperature & humidity sensor and Bluetooth communication with a phone. We use a BLE-Nano here, but you can also use a regular Arduino … Continue reading Tutorial: build a connected temperature sensor
Tutorial: build a distance sensor with an alarm
Introduction to Arduino and programming . There is also a “quick walk-through video” of this tutorial. My practicals which use this tutorial have an introductory presentation (pdf). We will build a distance meter in this tutorial. It uses an ultrasonic distance sensor to sense the distance to an object nearby. It consist of the following steps: … Continue reading Tutorial: build a distance sensor with an alarm

Options for additional components and power for the Arduino
What options are there for the use of motors in our project? There are many types of motors. There are 3 basic types (more info): Servo motors Stepper motors DC motors Most light servo motors can be used directly with an Arduino (no motor driver/controller required). For some heavier types and for many DC and … Continue reading Options for additional components and power for the Arduino
Bluetooth communication between an App built with App Inventor and the BLE-Nano board
This tutorial describes how to build an electronic circuit with an RGB LED (a LED that can change color), and change its color using an App. It also demonstrates two-way communication over Bluetooth LE between an App built with App Inventor and the BLE-Nano board. The BLE-Nano board is basically an Arduino Nano with an … Continue reading Bluetooth communication between an App built with App Inventor and the BLE-Nano board
