Arduino- Introduction- Open-source electronic platform. - Uses simple programming language to input commands, like instructions to turn on a LED light and turn it to an output using simple hardware pluged in to the Arduino Board. - The examples in this document show how a few ways Arduino can be used in Architecture and Design.

Note: The content of this document has been acquired from Arduino.cc. For more information please visit https://www.arduino.cc/

Computer- For Input- Any form of computer will be needed to input the required script to the Arduino.

Arduino Board- To Process Input and Output- A range of Arduino Boards are available to perform the required activities. Note: Range of tasks will vary according to the capabilities of the Arduino Board.

Sensors- To Read Data or Ouput Data- A wide variety of Arduino microcontrollers and sensors are available to read input and output data.- Example: LED sensors (above).

Hardware

Arduino IDE- Programming Language- Input data and tell the Arduino what through easy-to-use code/ programming language and Arduino Development environment.

Software

Why Use Arduino?- Affordable - Arduino Boards are relatively more afforable than other microcontroller based platforms.

- Cross-Platform - Runs on Windows, Mac OS and Linux.

- Easy-to-use Software - Easy to learn for beginners, yet adaptable to advanced programmers.

- Open Source Software - Open source properties makes the Arduino IDE software easily extensible by experienced programmers through C++ libraries.

- Open Source Hardware - All Arduino boards are publised under Creative Commons license. Therefore any experienced circuit designer can make their own version of an Arduino module.

Arduino v. Rasberry Pi- Arduino- Microcontroller motherboard (simple computer). - Capable of doing simple tasks, like reading temperature, pH balance, LED fade, simple robot movements etc. - Can run only one program at a time, in a repetitive manner. - Easy to use.

- Rasberry Pi- General Computer with Linux operating system. - Capable of running more complex tasks like hard calculations, complex robotic movements etc. - Can run multiple commands or programs like a regular computer. - Relatively more difficult to use.

Arduino + Design- Examples- The following examples show how Arduino has been used in Architecture and other design related fields at Iowa State University and other designers and architects around the world.- The examples range from miniature robots to large scale pavilions and installations.

80|35 Pavilion- Fabricating Potentials Studio, Spring 2016, Iowa State University

Arduino was used in this project to program the RGB LED strips, embedded in each module of the pavilion. The programmed LEDs reacts to noises around the pavilion, giving the pavilion the vibrancy of the festival itself.
