In the recitation, we are asked to build 3 simple circuits. In high school I had some experience building the circuits but I never used a bread broad. I used to see every wire I connected. The problem with bread broad is that I cannot see every wire, so the first step is to get familiar with how the bread broad is connected within. The second step is to know what the materials look like. me After acknowledging these, it becomes easy for me and my partner to build the circuit.
These are materials needed:
- 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)
The first circuit we built:
As we are building, the first problem occurs is that we do not know how to make things grounded. We even want to connect the wire onto the floor. With the help of Inmi, we know that the ground is the cathode of the bread broad. And it’s worth noted that always use a darker color to ground.
This is the second circuit:
Another problem is how to put the switch. We think how we connect all the materials are right but the light is always on, it doesn’t control by the switches. Later after we looked at the diagram we found out that the four legs are not equal. A and D is connected and B and C is connected. You can only place the switch in a certain way. We then change the way we put the switch and it works.
This is the third circuit we built:
Answer to the question: 1. Interaction is a process of act and react. That is to say, one throw a message to the other and the other one process the massage and throw it back. When building circuits, we give the circuits messages and get feedback from it. If the light is not on or there’s no sound in the speaker, we will improve on our currently built. So it’s a way a interact.
2. Speaking to interaction and art, what most impressed me is teamlab’s work. I went to an exhibition of teamlab in shanghai this summer. It was really beautiful and interactive. The images on the wall will change according to your different pose and position.
