 Arduino晶片可以買Arduino mini來拆,就不用再灌燒錄程式進去了
 注意:本Layout沒有設計燒錄程式的線路進去!




 本layout圖的電路圖是參考Arduino官方提供所改成的
Layout

製作好後

3.開通晶片與上傳程式
準備USB to TTL燒錄器(CP2102 Arduino pro mini)
下載並安裝該燒錄器驅動程式
將燒錄器的RxTx接再貼片的D8D9上,燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND
開通藍芽晶片
下載USR-TCP232-Test V1.4.exe程式
設定好序列埠,選擇燒錄器的port(COM?)
設定好胞率12500
HEX取消打勾
Open
CMD輸入
$$$
S-,<你要設定的名子> <CR>  /*設定BLE名字為<你要設定的名子>,<CR>是按Enter換行就可以了*/
SS,C0 <CR>  /*C零喔!*/
--- <CR>

/*每次輸入指令成功的話會回覆"CMD>AOK"*/

/*這樣基本上設定完成*/
上傳Arduino程式
將燒錄器的RxTx接再貼片的TxRx上,燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND
打開Arduino
工具->開發粄->選擇Arduino Pro or Pro Mini
工具->序列埠->選擇燒錄器的port(COM?)
上傳程式碼
#define sensor_pin A1
#include <SoftwareSerial.h>   // 引用程式庫
#define rxPin 8
#define txPin 9                                                                   
SoftwareSerial BT(rxPin, txPin);

void setup()

  Serial.begin(9600);
  Serial.println("BT is ready!");
  pinMode(rxPin,INPUT);
  pinMode(txPin,OUTPUT);
  BT.begin(115200);
}

void loop()
{
  int sensor_value = analogRead(sensor_pin); // 讀取FSR 
  double val  = sensor_value *3.3/1024;
  Serial.println(val); 
  BT.print(val);
  BT.print("\n");
  delay(100);
}
4.完成


貼片操作
有線連電腦操作:
將燒錄器的RxTx接再貼片的TxRx上,燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND
打開Arduino
工具->開發粄->選擇Arduino Pro or Pro Mini
工具->序列埠->選擇燒錄器的port(COM?)
看數據呈現
工具->序列埠監控視窗
看數據圖的呈現
工具->序列繪圖家

無線連手機操作:
將直流電源3.3V正極接在貼片的EN上、直流電源負極接在GND
(電池(3.3V~12V)或是燒錄器皆可)
打開手機APP BLE Scanner
選擇該貼片名稱的connect
COSTOM SERVICE
CUSTOM CHARACTERISTIC I圈圈便可以看到及時數值


應用
可以在該兩個點上焊上只需要兩個點的簡單sensor EX:溫度sensor
在有供電狀態下就可以貼在任何地方持續量測數值,並且可以用BLE傳送數值
但會需要更改Arduino上傳進去的程式(廢話)
