First week recitation
In the first week recitation, I and my partner built 3 circuits and soldered out a button with the help of teaching assistant. The details are as follows.
Materials
- 1 * Breadboard
- 1 * LM7805 Voltage Regulator
- 1 * Buzzer
- 1 * Push-Button Switch
- 1 * Arcade Button
- 1 * 220 ohm Resistor
- 1 * 10K ohm Resistor
- 1 * 10K ohm Variable Resistor (Potentiometer)
- 1 * LED
- 1 * 100 nF (0.1uF) Capacitor
- 1 * 12 volt power supply
- 1 * Barrel Jack
- 1 * Multimeter
- Several Jumper Cables (Hook-up Wires)
Diagam 1
At the first we made a careful study of the diagram as well as found all components, we met difficulties for misunderstanding the breadboard. Thanks to the help of the assistance we finally understand the invisible connection in the board. We also put effort into learning how to use wires to connect each component . After several attempts, the buzzer did work!

Soldering
This little success really inspired us to head forward to the next two circuits and soldering.To begin with, I used the holes on the scissors to peel the rubber off the wires, while my partner heat up the soldering iron. We really met a problem when there is no clear button left, lucky, a patient teacher helped us to clear the tin left in the hole on the iron bar. Then we carefully putting the a wire through the hole, heating the tin bar, soldering it by melting tin, and the other side.
Diagram 2&3
The circuits 2&3 are lamp and dimmabe lamp. firstly, We used the multimeter to figure out the resistance value of the two resistance. The second circuit is quite successful, and we did not remove all the components for teachers’ suggestion. However, at the third circuit, we get stuck at the Variable Resistor , it really took us several time to work it out.

Answers to Questions
Q1:Interactive is the conversation between two actor, in today’s recitation, this two actor are the circuit and us. For the circuit, the changes on the components are the input, or “listen”. The electric current passes through the wires. that might be the process, or “think” . The reactions of the effectors are output, or “speak” For us, we observed the reaction of the effectors , think about the proper time to operate the control system. we finally made our decision and operate it, we “speak” .
Q2:Interactive design is using devise to realize our ideas. Physical computing is processing in deed. Interactive art would not come to reality if we could not make a Interactive design makes possible the communications between people and interactive devices.
