Recitation 2:Arduino Basics by Molly (Weiyi He)

  1. Fade

Reflections:

1) I started to realize that actually, pins can provide power, just as pin 9 did in this circuit.

2)Led isn’t mirror, I have to pay extra attention to the direction–which leg should go to positive.

*Be careful how the legs are plugged to connect the wires correctly.

Reflections: 

1) The circuit is rather complicated and there could be a short circuit. Therefore, double check the circuit before plugging into power. We had a short circuit and burnt a wire (maybe additionally, an LED). It led us to have a long time of debugging (finding where is wrong with the circuit)

2)When is debugging the circuit, certain strategies could be implemented. They are a reflection of one’s experience in dealing with circuits. So practice more, and I will become a more professional builder. And don’t be afraid of making mistakes.

4. Interaction is between various entities, one take an action, the other would give a response according to some conditions.

5. I want the 100,000 LEDs to be on a random street. It is a display of people’s emotions when one walk past them. This is when the most private part being showcased to the community of people that happen to be at the same spot or to pay attention to the person’s well-being. It could be a test of whether the surrounding people would take action toward the person’s emotions being displayed. It could also be research into how people mostly or randomly feel when they are walking on a random street.
