processing 用來送串列資料

Arduino IDE 用來寫程式

python 用來抓取網頁更新

processing 間隔5秒送出 ACSII 1

import processing.serial.*;

Serial ser;

void setup () {

size(400,400);

ser= new Serial(this, "COM7", 9600);

for(;; delay(5000)){

ser.write(49);

//delay(150);

//ser.write(76);

}

}

void draw () {

line (0,0,200,100);

}

Arduino 偵測收到 1 就搖搖鈴

#include <Servo.h>

Servo myservo;

const int RINGTIMES = 5;

byte b = 0;

void setup() {

Serial.begin(9600);

myservo.attach(14);

myservo.write(90);

}

void loop() {

while (Serial.available()) {

b = Serial.read();

delay(2);

}

if (b == 49) {

ring(RINGTIMES);

b = 0;

}

}

void ring(int times){

for(int i = 0; i < times; i++){

myservo.write(125);

delay(150);

myservo.write(90);

delay(150);

}

}

用spyder 撰寫 python程式，產生一個網頁計數器

from flask import Flask

app = Flask(__name__)

count = 0

@app.route('/')

def index():

with open('./counter.txt','r') as f:

count = int(f.readline())

count = count + 1

with open('./counter.txt','w') as f:

f.write(str(count))

return "<p>Hello visitor. There are "+str(count)+' visitors </p>'

if __name__ == '__main__':

app.run(debug=True)

用 processing 讀取 計數器的值 如有修改 就送出 "1" 到 串列埠

import processing.serial.*;

Serial ser;

String lines[];

int counter = 0;

void setup(){

ser = new Serial(this, "COM7",9600);

surface.setVisible( false );

for(;; delay(5000)){

lines = loadStrings("c:\\1\\counter.txt");

print(int(lines[0])," ");

if (int(lines[0]) != counter){

counter = int(lines[0]);

ser.write(49);

}

}

}

void draw(){

}

Arduino 接收串列埠，如果讀到 "1" 就 搖鈴

#include <Servo.h>

Servo myservo;

const int RINGTIMES = 5;

byte b = 0;

void setup() {

Serial.begin(9600);

myservo.attach(14);

myservo.write(90);

}

void loop() {

while (Serial.available()) {

b = Serial.read();

delay(2);

}

if (b == 49) {

ring(RINGTIMES);

b = 0;

}

}

void ring(int times){

for(int i = 0; i < times; i++){

myservo.write(125);

delay(150);

myservo.write(90);

delay(150);

}

}
