【Tutorial】Linkit 7697打造遠端遙控智能燈座(Part 2)

作者:Ches

在先前已經寫過一篇使用Linkit 7697打造遠端遙控智能燈座,而這一篇是第二部分。這次手作了35 PCS課堂上使用,包括11Maker Faire Taipei展覽樣品:

和鎢絲燈泡一起打包過後,就像準備出貨,只是難看了點:

工作桌凌亂不堪,但為了就是讓學員一次就上手!特地準備了九支程式、電路圖說明與Layout走線,要在三小時完全學會,而且當天會有小鮮肉助教,把教材給他之後,我就可以喝飲料看漫畫了。希望之後大家上完整個系列課程之後,大家能多多關心自己家中的長輩 。

以下程式可以按下dab調光

操作影片如下:

給大家需要的公式:

int pinLed = 14;

int PWM = 9; // PWM pin

int dimming = 40;  // Dimming level (0-128)  0 = ON, 128 = OFF

int flag1=0,flag2=0,flag3=0;

void setup(){

Serial.begin(9600);

pinMode(2, INPUT);

pinMode(pinLed, OUTPUT);

analogWrite(PWM, 55);  //setting PWM speed

Serial.println(“Hello”);

}

void loop(){

int switchStatus = digitalRead(2);

String s = “”;

 

while (Serial.available()) {

char c = (char) Serial.read();

if(c!=’\n’)

{

s += c;

}

delay(1);

}

if(s==”d”){

flag1=1;

flag2=0;

flag3=0;

dimming=40;

Serial.println(s);

}

if(s==”a”){

flag2=1;

flag1=0;

flag3=0;

dimming=30;

Serial.println(s);

}

if(s==”b”){

flag3=1;

flag2=0;

flag1=0;

Serial.println(s);

}

if(switchStatus==HIGH && flag1==1)

{

 

Serial.println(“ddd”);

int dimtime = (65*dimming);    // For 60Hz =>65

delayMicroseconds(dimtime);    // Wait till firing the TRIAC

digitalWrite(pinLed , HIGH);   // Fire the TRIAC

delayMicroseconds(8.33);         // triac On propogation delay

// (for 60Hz use 8.33) Some Triacs need a longer period

digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

}

if(switchStatus==HIGH && flag2==1)

{

 

Serial.println(“aaa”);

int dimtime = (65*dimming);    // For 60Hz =>65

delayMicroseconds(dimtime);    // Wait till firing the TRIAC

digitalWrite(pinLed , HIGH);   // Fire the TRIAC

delayMicroseconds(8.33);         // triac On propogation delay

// (for 60Hz use 8.33) Some Triacs need a longer period

digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

}

if(switchStatus==HIGH && flag3==1)

{

 

Serial.println(“bbb”);

digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

}

}

以下程式可以做出AC呼吸燈泡模式

將%Localappdata%\Arduino15\packages\LinkIt\hardware\linkit_rtos\0.8.4\cores\arduino\wiring_interrupt.c

裡面的eint_config.debounce_time = 50; // debounce time unit: ms

50改為0

可以在C槽中找

操作影片如下:

下面是需要的公式:

int pinLed = 14; //output pin

int flag = 0;

int dimming = 128;  // Dimming level (0-128)  0 = ON, 128 = OFF

int brightness = 40;    // how bright the LED is

int fadeAmount = 1;    // how many points to fade the LED by

void setup()

{

pinMode(pinLed, OUTPUT);

attachInterrupt(2, interrupt, RISING); //using interrupt

Serial.begin(9600);

}

void loop()

{

if (flag == 1 )

{

// change the brightness for next time through the loop:

brightness = brightness + fadeAmount;

dimming=brightness;

Serial.println(brightness);

int dimtime = (65*dimming);    // For 60Hz =>65

delayMicroseconds(dimtime);    // Wait till firing the TRIAC

digitalWrite(pinLed, HIGH);   // Fire the TRIAC

delayMicroseconds(8.33);         // triac On propogation delay

// (for 60Hz use 8.33) Some Triacs need a longer period

digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

// reverse the direction of the fading at the ends of the fade:

if (brightness <= 10 || brightness >= 100)

{

fadeAmount = -fadeAmount;

}

flag = 0;

}

}

void interrupt()

{

flag = 1;

}

這次是初階課程,如果控制30顆燈泡同時閃爍或亮滅,會挺壯觀,但可惜的是,MQTT要等到進階課程才會教到。
