In this tutorial, we will create a simple text-based calculator. It’s meant to practice basic Java syntax, like println(), if- and basic arithmetic. The resulting calculator can only do the 4 basic operations and it does not recognize fractions. It…
Getting a WS2812 based led strip to work using the FastLED library.
Learn how to create a simple calculator in Java.
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…
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…
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…
Introduction to Arduino and programming . There is also a “quick walk-through video” of this tutorial (but it is rather old). We will build a distance meter in this tutorial. It uses an ultrasonic distance sensor to sense the distance to…
If you keep getting the error below (or a similar one) when trying to upload your sketch, read this article. Try the troubleshooting steps below in order. If it still fails, contact us and describe what you tried (which steps).…
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): Most light servo motors, like the common SG90 (which you can borrow from Fjodor), can…
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…
