This article highlights four different ways you can make sounds with the Arduino or play music. It starts with the easiest one: (1) adding a small buzzer, then (2) a standard loudspeaker, then (3) using your smartphone as the speaker…
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…
In a previous tutorial “build a distance sensor with an alarm” we used an Arduino Nano (coded in a C-variant). Now, we will do the same with a Raspberry Pi Pico and CircuitPython, a version of Python which runs on…
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…
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…
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 page explains the use of the TCS3200 colorsensor and shows how to create a small holder for it, which can be mounted on the Rover Car. It is also possible to just use the holder (without connecting it to…
Learn how to build a remote controlled Rover car with Lego Mindstorms, with an Arduino ‘brain’, which can be remote controlled via Bluetooth with a phone. This guide uses parts from the Steering rover example on nxtprograms.com. It is also…
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 Install the MIT AI2 Companion app on your phone. To be able to identify your NXT (if…
