遙控變色燈

相信很多人去逛IKEA都對這蠟燭台很有印象,感覺很好看,但又不知道買了要做啥.

顏色還很多種可以挑選呢.燭台.感覺有點危險,

或許拿來當營燈也不錯,網路上有很多達人都改裝成不同的LED.

要是跟大家都一樣,創意算是抄襲的.

所以囉.來點不一樣的.我的版本是遙控變色LED燈

材料如下:
IKEA蠟燭台,
Arduino Nano控制板,
3.7V手機電池,
5V升壓板,
AT89S52 315M遙控模組,
NeoPixel LED Ring,
泡棉一塊....

預計規劃的功能如下
當按下遙控器按鈕A 開啟紅燈,再次按下則關閉紅燈.
當按下遙控器按鈕B 開啟藍燈,再次按下則關閉藍燈.

當按下遙控器按鈕C 開啟綠燈,再次按下則關閉綠燈.

藉由ABC三個按鈕的交叉組合可以出現以下七種顏色變化

如按鈕D啟動, 則呈現DEMO展示,呈現彩虹色環的旋轉變化

程式碼的部分直接使用Adafruit_NeoPixel的DEMO code.小改一下很快就完成了.

剩下就是買零件組合.

這回要利用廢棄的手機電池當作電源的來源,需要是3.7V轉5V的電源供應機制.

如果不想用手機電池,其實可以用三顆1.2V的充電電池搭配電池盒與升壓板組合.
但考慮到只有狹小的燭台頂部空間可以收納這些零件.還是使用手機電池好了.

以下是直接修改DEMO code的文件加入AT89S52 315M的控制於PIN8/9/10/11.
NeoPixel的控制接在PIN6,總計目前使用五個訊號端.
不過.目前手上還有一個G Sensor.可以考慮一下放進去.如果燈發生搖晃時.發生閃爍嗎?不過Arduino的I2C我還不懂.這可以當作下回的練習.

#include 

#define PIN 6

// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(16, PIN, NEO_GRB + NEO_KHZ800);

// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel.  Avoid connecting
// on a live circuit...if you must, connect GND first.

Linkit-7688 duo & Arduino IDE Error.

Linkit-7688 duo可以使用 Arduino IDE操作使用,用法就跟Arduino完全一樣
但事前的準備可多囉,首先是IDE的部分要追加LinLit 7688的資料庫(細節可以參考以下網址)
http://oranwind.org/linkit-7688-linkit-smart-76887688-duo-ji-chu-jiao-xue/
直到能夠出現以下畫面的操作參數,方可將程式碼上傳,

如操作這一部分應該只用到MCU(Microcontroller Unit),也就是ATmega 32U4.
跟7688的強項完全無關,只能說是Arduino的附身.

但要上傳Code可能會出現很可怕的錯誤訊息.可能看不懂對吧
https://labs.mediatek.com/forums/posts/list/4392.page
其中有個描述
USBCore.cpp: In function 'int USB_RecvControl(void*, int)':
這段描述就直接指出USBCore.cpp這個檔案中的描述有問題

總之得要手工微調檔案內容了.先找到檔案位置.
C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino
開啟USBCore.cpp這個檔案.
找到第430以及435行,將Auto改成int後存檔
就可以解決這個問題了.

Arduino lightsaber Debug

終於等到材料了實際運作上有幾個問題

1.購買的LED尺寸規格小於預期, 48顆LED的長度才能達到60公分.因此全部的Digital pin都要用於LED使用.所以要用於作業的LED串就需要一點勞作的實力了.

一整包的LED要如何排排站好呢?用手抓,別鬧了.烙鐵溫度300度,

至於要如何快速又簡單的將LED串接起來,首先就要先設計製具,
以下直接找個瓦楞紙盒,先規劃好距離,針對LED的位置開孔.
接著貼上一層鋁箔.散熱使用,避免烙鐵直接將瓦楞紙燒毀.

瞧,排隊整齊劃一,輕輕一點錫就接合焊好,輕鬆愉快.

速度快的話20分鐘就弄出這麼多組啦.

2. MP3 module未能如期發出聲音來.可能是程式碼有問題,或是IC的使用上還需要花點時間認識.最後重新改寫控制,先刪除MP3 player的部分,並追加新的LED控制pin,以及一分鐘無任何震動後關閉的設定.
