Fab Academy 第十六周：界面和應用編程

01-28

這周學習界面和應用編程

實踐作業

這周的作業是

為輸入/輸出設備寫一個應用程序

為之前做的這個檢測光線的板子做個小應用好了。

先試著讓板子跟串口通訊，看看元件是不是正常傳送檢測值。

#include "SoftwareSerial.h"n nconst int analogInPin = A3; // Analog input pin that the potentiometer is attached tonint sensorValue = 0; // value read from the potn nconst int Rx = 2; // this is physical pin 7nconst int Tx = 7; // this is physical pin 6nSoftwareSerial mySerial(Rx, Tx);n nvoid setup() {n pinMode(Rx, INPUT);n pinMode(Tx, OUTPUT);n mySerial.begin(9600); // send serial data at 9600 bits/secn}nnvoid loop(){n sensorValue = analogRead(analogInPin);n mySerial.println(sensorValue);n delay(500);n}n

光電晶體管工作正常。

下一步，在 processing 裡面寫界面的程序。當檢測到光線變暗時，界面提示「-_- Its dark!」，如果光線變亮，提示「its getting light 」：

The code:

import processing.serial.*;nSerial myPort;nint lf = 10;n nvoid setup(){n size(300,300);n myPort = new Serial(this,"/dev/tty.usbserial-A400gwhT",9600);n textAlign(CENTER, CENTER);n fill(255);n textSize(20);n}n nvoid draw(){n while(myPort.available() > 0){n String str = myPort.readStringUntil(lf);nn if(str!=null){n int value = Integer.parseInt(trim(str));n n if (value >900) {n print("its dark ");n println(value);n background(0,0,0);n text("-_- Its dark! ",150,120);n text(value,150,200);n } n else{n print("its getting light ");n println(value);n background(204,153,0);n text(":P Its getting light ",150,120);n text(value,150,200);n }n }n }n}n
