Components in the circuits: Resistor, LED, capacitor, voltage regulator, variable resistor, push-button, speaker, power, wire.
Resistor: A resistor is a two-terminal electrical component that resists the flow of electricity and can be used to control the flow of current.
LED: a light that examines the buildups of the circuit. If the circuit is built up successfully then the LED should blink.
Capacitors: store electricity and can also be used to stabilize the flow of electricity. Voltage regulator: it is used to regulate voltage levels.
Variable resistor: attached to a knob that can output an adjustable voltage.
Push-button: it is used to trigger the system.
Speaker: it is used to play sounds when electricity is pushed through wires.
Power: Gives the circuit abilities to function. Such as producing sounds, blink, etc.
Wire: Carries power from one point to another point.

Throughout the entire building circuits process, we have encountered several obstacles where the circuits did not function properly. For example, in the doorbell circuit, the speaker did not work at first. We accidentally connected the wires in the wrong direction. We asked the LAs for help. And they kindly reminded us that we always need to connect the wires back to the ground.
The three circuits we have built during recitation time clearly show interactivity. Each group member had to do hands-on works in order to successfully build the circuits. We have to connect wires, insert all the components that each circuit needs to have. For the doorbell circuit, we had to press the push button in order for the circuit to produce an audio sound.
Interaction designs are usually physically made by the artist. In Zack Lieberman’s video, he illustrated an example of how they helped a paralyzed graffiti artist to keep on drawing while he is in a hospital room. They built up a system that allowed the artist to just make eye movements to draw. And the team would project those drawing on many walls throughout the city. He said at the end of the video “We’re helping people to breathe.” Interaction designs help to open up possibilities in impossible situations.
