[穿戴科技] Adafruit FLORA初接觸

Adafruit出一款大約美金20美元的穿戴科技模組，我們稱它為 FLORA，讓晶片相容於開放式硬體Adruino。
在網站https://www.adafruit.com/products/659有詳細的說明，FLORA體積很小和重量很輕，直徑1.75“，重量約4.4克。對FLORA系列而言，擁有配件包括：最好的不銹鋼線、感知器、GPS模塊和可鏈接的LED NeoPixels。2015年5月12日開賣的FLORA V2是採用micro-USB介面。




初學者的教材在https://learn.adafruit.com/getting-started-with-flora。 Arduino IDE版本至少要在 1.6
(含)以上。
軟體的安裝在https://learn.adafruit.com/adafruit-arduino-ide-setup/arduino-1-dot-6-x-ide。要在Arduino IDE中使用Adafruit FLORA，您必須在"檔案->偏好設定"功能選項，打開偏好設定的功能表，並在額外的板子管理員網址中輸入：https://adafruit.github.io/arduino-board-index/package_adafruit_index.json字串。

另外也要記得裝FLORA的驅動，可參考https://learn.adafruit.com/adafruit-arduino-ide-setup/windows-setup。

接下來就可以打開Arduino IDE，選擇範例檔Blink。

其程式碼如下：

/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and

  Leonardo, it is attached to digital pin 13. If you're unsure what

  pin the on-board LED is connected to on your Arduino model, check

  the documentation at http://www.arduino.cc

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board

void setup() {

  // initialize digital pin 13 as an output.

  pinMode(13, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(1000);              // wait for a second

  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW

  delay(1000);              // wait for a second

}

因為板子內建LED在D7，所以必須把上面範例中腳位13改成腳位7。

// the setup function runs once when you press reset or power the board

void setup() {

  // initialize digital pin 13 as an output.

  pinMode(7, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(1000);              // wait for a second

  digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW

  delay(1000);              // wait for a second

}
