We first built the button of the circuit. It was easier than building the circuit itself as long as we were very careful. Reading the circuit diagrams as well as connecting all the components on the breadboard was difficult as it took us a long time to understand how the breadboard works. Plus, we ran out of space to plug the cables onto the breadboard so we need to adjust some of them to have enough space for all the components.
Step1
Step2
Step3
- Breadboard: connects all the stuff and let electricity flows through
- Buzzer: makes sounds
- Resistor: reduces current so the LED doesn’t get burned
- Variable Resistor (Potentiometer): provides adjustable amount of resistance
- LED: light. See if the circuit works
- Button: switches on/off the circuit
Question 1
The resistor helps reduce the amount of current that passes through the LED, so the current won’t exceed the limit and damage the LED.
Question 2
Question 3
According to the author, “interaction is a cyclic process in which two actors alternately listen, think and speak.” The circuit we build today doesn’t feel like a strong interaction because it only listens to our order, process after the circuit connects and speak(light up the LED and make sounds). When we receive its signal, we can decide if we switch it on again or we stop. Even we speak(push the botton) again, we are not building it on top of what the circuit just spoke, it feels like another beginning of a conversation. So I would consider it a low degree of interactivity.
Question 4
The EyeWriting that Zack Lieberman and his team created is really impressing. They have used the cheap web cam together with the software that allows the sensors to track the movement of the graffiti artist’s eye. It’s a good example that through sensors and the software they designed(Physical Computing), artist can create arts in an interactive way. When the device track down what the users are drawing, it processes and displays the work. The interaction goes on an on until the art work is done.
