Q1:What is the function of resistor R1 To limit the current pass into the circuits. Because if we review the whole circuit we can find that the circuits are composed of LED diodes, batteries, buttons, wires. And the diode has a limit interval of voltage. “There is a specification for diodes called the characteristic (or recommended) forward voltage (usually between 1.5-4V for LED)”(Skill Level: Beginner, & | December 02, 2010 | 42 comments. (n.d.). Led current limiting resistors – SparkFun Electronics. Retrieved February 17, 2022) For diodes if we exceed the maximum amount of voltage, the resistance will drop off and current will increase and burn the diode. Therefore, according to Ohm’s law: V=IR that use the resistors will keep current in a rationale range and avoid burn the diode. Q2: Following the circuits to draw the diagram by yourself 
Q3: After reading The Art of Interactive Design, in what way do you think that the circuit you built today includes interactivity? Which degree of interactivity does it possess? Please explain your answer. In today’s project we built a little monster by me and my partner Stephen. We got a button and if you click the button the buzzer will make the sound of buzz, just like the yell of a Monster. And the lights inside of the circuits will turn on to demonstrate that the circuits are working. According to the concept in “art of interactive”, to prove this project includes interactivity, we need to separate the whole process into three steps and we assume that the person who gives the action is named “A”. Step one: “A” click the button, circuits are complete and current is flowing inside of the circuits. Step two: The buzzer and light receive the electricity. Step three: electricity powers the buzzer and light and makes it work. So in this way i think that because there is no feedback which is given by computer program. The interactive degree of our project is low. Q4: How can Interaction Design and Physical Computing be used to create Interactive Art? You can reference Zack Lieberman’s video or any other artists that you know. I’ve read a video of an artists named Refik Anadol. He’s surreal installations is made up of millions of tiny pieces. Every point represent a piece of data that he’s fed through a neural network . He try to make the data become to pigment. And every time he input the new image or video into the algorithm and the program will achieve the process of self learning and transmit these resources into data and present it mostly on the wall of some building or sculpture。In his idea, that he used to use wind, cloud, water to inspired him and give him some inspiration which he has a idea in his mind that use the wind as a data and also a pigment. That the outlook of his artwork will change with temperature. So firstly, their team collected a one year long data of wind from Boston, which consist of dust speed, direction and even temperature. All these data combine together and show us an abstract image which were automatic design by the algorithm. He believe that this technology will help human to obtains more unexpected discovery.
