During the recitation, we were required to build 3 circuits with the Arduino.

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

circuit 1: Fade

When I build the circuit, I first make a small mistake that the resister and the LED were disconnected. After I found the mistake, the circuits worked.

Circuit2: toneMelody

We didn’t meet difficulties in this circuit and it worked.

Circuit 3: Speed game

This is the most complicated one and here is the schematic circuits.

the wires are complicated and we tried about 3 times and it was really fun. I learned that you need to be really careful when building the circuits and alwais remember to put semicolon at the end of the lines.

Answers

1）We interact with the computer and then the computer does what we want it to do and then interact with other people. Code builds a bridge between input and output and allows us to express ourselves and get feedbacks.

2) To control the current in a small level so it won’t cause a short circuit.

3) I want to create a dragon using the changing of the color and the movement of the LEDs. If possible, I want to put it in the water so it can show a vivid scene that a dragon is jumping through the water.
