3D Traffic Lights
Did you know? An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. A burglar alarm, an in-car cruise control system, a speedometer on a bike, a…
3D Solar System
In this blog post we will use Glowscript to create a 3D animation representing the revolution of the Earth around the Sun, and of the Moon around the Earth. Earth Revolution First, let’s calculate the angle of rotation needed to…
3D Tetris Shapes
In this blog post we will use Glowscript to create a 3D animation representing the various shapes used in a game of Tetris. Our aim is to recreate each shape by joining several cubes together. We will then create a…
3D Animation : Moon Phases
In this blog post we will use Glowscript to create a 3D animation representing how we perceive the moon from Earth throughout its cycle. Our aim is to represent a 3D sphere and to progressively change the direction of the…

The Collatz Conjecture
The Collatz conjecture is a famous mathematical mystery that has yet to be solved. It is named after Lothar Collatz a German mathematician, who first proposed it in 1937. It is based on the following number sequence: Start with any…
Merry Christmas
For this challenge we are going to create Christmas Cards using Python turtle. We will use the random library to create unique cards. Starry Night Our first card consists of creating a starry night scene. This card is using: A…
Sequencing, Selection & Iteration
When you write lines of code, there are three ways you can control the order these lines will be executed by the computer: Sequencing: This means that the computer will run your code in order, one line at a time…
