The course is intended to equip students with the knowledge and skills necessary to design, build, and program interactive devices that respond to their environment. This article aims to provide a comprehensive guide to DDA-254 Physical Computing, covering its definition, principles, components, applications, benefits, and challenges.
What is Physical Computing?
Physical computing refers to the design and construction of interactive systems that sense and respond to the physical world. Physical computing systems typically consist of sensors that detect changes in the environment, microcontrollers that process sensor data, and actuators that respond to the data by controlling physical devices. Physical computing systems can be as simple as a light sensor that turns on a lamp when it gets dark, or as complex as a robot that can navigate through a maze.
History of Physical Computing
The roots of physical computing can be traced back to the 1960s, when researchers at MIT’s Media Lab began exploring the use of computers as tools for artistic expression. The term “physical computing” was first coined in the early 1990s by researchers at the Interaction Design Institute Ivrea in Italy. Since then, physical computing has grown into a multidisciplinary field that combines computer science, engineering, and design.
Principles of Physical Computing
Physical computing is based on the following principles:
Components of Physical Computing
Physical computing systems typically consist of the following components:
Sensors and Actuators
Sensors are devices that detect changes in the environment and convert them into electrical signals that can be processed by a microcontroller. Actuators are devices that respond to signals from the microcontroller by controlling physical devices. Examples of sensors include light sensors, temperature sensors, and motion sensors. Examples of actuators include motors, lights, and buzzers.
Microcontrollers
Microcontrollers are small computers that can be programmed to control sensors and actuators. Microcontrollers typically have input/output pins that can be connected to sensors and actuators, as well as built-in analog-to-digital converters that can be used to read analog sensor data. Examples of microcontrollers include Arduino, Raspberry Pi, and BeagleBone.
Programming Languages
Physical computing systems can be programmed using a variety of programming languages, including C, C++, Python, and Scratch. Arduino, a popular microcontroller platform, uses a simplified version of C++.
