範例02_連接Arduino_數位輸入與類比輸入
歡迎來到第一個範例!
首先請取得 Arduino 1.8.5,並安裝好驅動程式之後燒錄 [StandardFirmata] 程式,這個小程式可以回應來自外部的所有呼叫。是相當好用的範例,當然也有其限制,後續會再深入說明。範例路徑為:File / Examples / Firmata / StandardFirmata

接著要在設定 Processing IDE中設定 Arduino 函式庫。請開啟 Contribution Manager(Sketch / Import Library... / Add Library...)

按鈕未按下,可變電阻值 < 800

按鈕按下,可變電阻值 > 800

import processing.serial.*;
import cc.arduino.*;
Arduino arduino;
color off = color(4, 79, 111);
color on = color(84, 145, 158);
void setup() {
size(470, 280);
// Prints out the available serial ports.
println(Arduino.list());
arduino = new Arduino(this, Arduino.list()[0], 57600);
arduino.pinMode(6, Arduino.INPUT);
}
void draw() {
background(off);
stroke(on);
if (arduino.digitalRead(6) == Arduino.HIGH) {
fill(on);
} else {
fill(off);
rect(400, 30, 50, 50);
}
if (arduino.analogRead(0) > 800) {
fill(229, 53, 53);
} else {
fill(152, 219, 31);
}
ellipse(280, 160, arduino.analogRead(0) / 8, arduino.analogRead(0) / 8);
}
