Interaction lab recitation 3 documentation blog post

Ultrasonic Ranger: [1] The Ultrasonic Ranger (AKA Ultrasonic Sensor OR HC-SR04) can be used to detect distance. To program the Arduino to work with this sensor, you can use this post or use the Ping example .

[1] (Arduino>File>Examples>0.6Sensors>Ping). In order for the HC-SR04 to work with the Ping code, you MUST connect both Trig and Echo to the same Digital Pin in your Arduino.

Question 1: What did you intend to assemble in the recitation exercise? If your sensor/actuator combination were to be used for pragmatic purposes, who would use it, why would they use it, and how could it be used?

We want to connect the led lights to the ultrasonic rangefinder to create a light that varies in response to the object’s distance. This device is suitable for use on a deep-sea sounder. The stronger the light is, the closer the object in front of you is. This device has the potential to act as a watchdog.

Question 2: Code is often compared to following a recipe or tutorial. Why do you think that is?

Code is similar to a recipe or tutorial in that it instructs a machine on what to do with its physical components in order to create outcomes as a function. In comparison, newborns have the instruments, in the shape of body parts, to conduct motor actions such as movement if their parents tell or teach them how. Similarly, computers and other types of hardware, such as the arduino, can transmit electricity via different hard components to achieve diverse functions, but they can’t unless someone, in this instance code, teaches them how to direct their signals and electricity.

Question 3: In The Language of New Media, Manovich describes the influence of computers on new media. In what ways do you believe the computer influences our human behaviors?

I feel that the computer’s fast-forward features, as well as its access to social media, have introduced new hobbies and interests to computer users. Furthermore, improved computation enables people to build more algorithms and applications, allowing for greater creativity.
