1. Build Circuits
With Rannan
1) Fading Lamp
We learnt that power could directly come into the breadboard on the positive and negative lines like the last recitation and could also come through Arduino uno to power the components.
Roughly like the picture below, we got clear about the Arduino parts. And we knew that GND in digital in/output group works the same as that in power group.
2) ToneMelody
It sounded but was not playing the expected melody. We failed to use the code, maybe…
We learnt the importance of selecting the board/uno and port/the USB one.
3) Speed Game
We separate the circuit into two parts and built that on the own side. Since we used switches outside the breadboard instead of the small button attached there, we flexibly handled the connections. But as we tested, only one side was counting the hits as shown below.
Then we checked and repaired the circuit from a wrong connection. And done.
2. Answers to Questions
1) Reflect how you use technology in your daily life and on the circuits you just built? Use the text Physical Computing and your own observations to define interaction?
I mainly use hands to input and eyes and ears to receive the output with tech devices. This speed game circuit receives my push and give me output by my multiple senses. The former two circuits still are limited to hands, eyes and ears.
Input, processing and output, these steps of an interaction via technological devices makes lifeless computing machines lively and friendly to us.
2) Why did we use the 10K resistor with the push button?
When switch off, the circuit is open and nothing goes to 11 or 10; then Arduino will be confused if there is no signal in.
3) If you have 100,000 LEDs of any brightness and color at your disposal, what would you make and where would you put it?
A screen. Where a screen is needed, say, PC, phone and ads board…
