Recitation 10

This combination of the Arduino and the Processing is actually a part of my final project. The circuits of the it are two buttons, when you press the button, it will blossom fireworks on the screen. So it is required to let the Arduino send the messages and the Processing will receive messages and appear fireworks with random colors.

Arduino:

#include “SerialRecord.h”

// Change this number to send a different number of values
SerialRecord writer(3);

void setup() {
Serial.begin(9600);
}

void loop() {
int sensorValue1 = analogRead(A0);
int sensorValue2 = analogRead(A2);

writer[0] = millis() % 1024;
writer[1] = sensorValue1;
writer[2] = sensorValue2;
writer.send();

// This delay slows down the loop, so that it runs less frequently. This
// prevents it from sending data faster than a Processing sketch that runs at
// 60 frames per second will process it. It also makes it easier to debug the
// sketch, because values are received at a slower rate.
delay(100);
}
