Recitation 2: Arduino Uno by Cathy Wang

Materials:
From Arduino Kit:
1 * Arduino Uno
1 * USB A to B cable
1 * breadboard
1 * buzzer
2 * LEDs
2 * 220 ohm resistors
2 * 10K ohm resistors
2 * pushbuttons
A handful of jumper cables

From cart:
2 * arcade buttons
1 * Multimeter (optional)
During this recitation, we were required to make three circuits. every time we connect the circuit as same as the instruction, so we make those three quickly. here are the three circuits:


The first one is quite simple. But at first, our LED isn’t bright. We checked many times and finally find out the problem: our LED is broken. After we changed a new one, this circuit worked.

The second one is also simple. we just change the LED with the buzzer and when the circuit is connected, the buzzer rang.

This one is a little complicated. With many wires to connect, we conncet them cautiously and imitate the picture on tinkercad.

Question 1:
I may use the busser circuit as a monitor in the house, like an alarm. when the stranger walks in without permission, the buzzer will ring. As the reading shows, interaction includes input, output, and processing (xx). Processing is an important part of interaction. Without processing, “interaction” will become a simple “reaction”. Processing, in another word, transforming is a key part of the interaction.
Question 2:
To share the current and protect the circuit, since the resistance of push-button is pretty small.
Question 3:
I will send them to the area which has fewer lights.
