# 4. Students Combining 3D Printing and Arduino

## 3D Printing & the Arduino Board

A desired outcome is a container that will perfectly fit an Arduino Uno R3 board, along with a push-button and LED light that both fit flush with the lid and are operational.

### Standards:

Measurement:

CCSS.MATH.CONTENT.2.MD.A.1
CCSS.MATH.CONTENT.3.MD.B.4
CCSS.MATH.CONTENT.4.MD.A.1
CCSS.MATH.CONTENT.4.MD.A.3
CCSS.MATH.CONTENT.5.MD.A.1
NGSS: 4-PS3-4.Apply scientific ideas to design, test, and refine a device that converts energy from one form to another

### Â Standards for Mathematical Practice:

CCSS.MATH.PRACTICE.MP1 Make sense of problems and persevere in solving them.
CCSS.MATH.PRACTICE.MP2 Reason abstractly and quantitatively.
CCSS.MATH.PRACTICE.MP4 Model with mathematics.
CCSS.MATH.PRACTICE.MP5 Use appropriate tools strategically
CCSS.MATH.PRACTICE.MP6 Attend to precision.
CCSS.MATH.PRACTICE.MP7 Look for and make use of structure

### Learning Objectives:

Students will design and produce a container for an Arduino Board
Students will design and produce a lid for an Arduino Board box with holes for a push-button and LED light
Students will use the Arduino board and push-button switch to power an LED light

### Recommendations:

Group Size: 2 to 4 students, depending on how many variations you would like students to compare within the class setting. For a smaller class, groups of 2 would be ideal.
Class Size: up to 36 students

### Materials Required:

Paper and pencil for drafting
Arduino button
Arduino LED light
Airwolf 3D Printer

Questions to Ponder:

What were some of the challenges in designing the container and lid?
What did you learn during the project?
Can you think of other projects forÂ students combining 3D printing and Arduino?
Did it come out the way you had planned and what did you learn about tolerances?
Did you know that the circuit board on the Airwolf 3D printer can be programmed in Arduino?Â
