3DX: Arduino Level 1 – 3D Literacy® Certification

3DX Logo

In the following sections you will find the resources necessary for 3DX: Arduino Level 1 class. There will be a project list, links of helpful resources, related files, and how-to videos. Students will utilize a variety of different open source technologies and online resources create their 3DX projects.

3DX Project Outline:

Project 1:  Blink with 2 LEDs

Project 2:  Traffic Light

Project 3:  Push Button with 2 LEDs

Project 4:  NeoPixels – Controllable RGB LEDs

Project 5:  Potentiometer with 5 LEDs

Project 6:  Servo Motor with Potentiometer

3D Literacy Workshops improve 3DX

Project 1: Blink with 2 LEDs

2 LED Project

2 LED project


The first project of 3DX students is the 2 LED project.  The goal is to learn basic 3D CAD, 3D printing, and 3D programming skills and learn how to fuse them together into a single project.  The 2 LED project will be built on their 3D Literacy® Maker Stations. Students will design a bracket for the 2 LED project, 3D print their part, learn how to wire and solder LED circuits. They will also be taught 3D Programming for the project by using an Arduino simulator tool and the actual Arduino integrated development environment for the programming. The 2 LED project will lay the foundation of skills required for all future projects in 3DX Arduino Level 1.
