In this week’s recitation class, we built three different circuits (actually are four, the fourth one is a kind of bonus circuit which we were tried to build).

The first circuit is a circuit with an LED diode inside. The blink pace of LED was controlled by the code program. It’s really normal because we’ve built several circuits before which were basically the same.

The second circuit contains a buzzer that can play melody according to the code. I think that this one is so much fun that I even try to change the code to let the buzzer play birthday songs.

The third circuit is a competitive interactive game with two-button. Click the button will connect the circuits and give the computer a signal to decide which side wins by recording the number of clicks. As the player presses the button, the current will flow through the whole circuit, and the computer will capture the signal and count the number in the program, shown on the monitor. Whether which side is the faster one presses ten times will make the light on.

 

 

Question 1:

I think we can use a paperboard button made of paper and the button system are also contains a buzzer which was the same as our previous projects. We can assume two players represent two “monsters”, and the number of the “monster” bites were represent their fighting capacity. When the two monsters are fighting, the buzzer will capture the signal and make sounds that seem like their yell. I think that if we can dig deeper that the definition of interactive, “interaction is ‘an iterative process of listening, thinking, and speaking between two or more actors.’”(Chris Crawford) The button can enhance the user’s Intuitive feelings which are their straightly feeling of their actions to products become more vivid and that is a part of listening. And just as the article said that the physical computer can divide into three different steps: input, processing, and output. I think that in my view, the goal of interaction design is to create products that enable users to achieve their objectives in the best way possible. In this way, the key point of this procedure is about human experiences which means that the input of our interactive design really makes a difference to the interactive degrees of our productions.

 

Question 2: 

In order to prevent short circuits. Because that is the pull-down resistor, when we click the button, the resistor will help restrain the current to prevent burning the circuits when the switch is closed while still biasing the pin to 0V when the switch is open.
