## RF24
[lib](https://github.com/nRF24/RF24)
使用2.4GHz進行通訊，SPI協定，共有4個強度可選，正電源只能接3.3V，單筆資料傳輸上限是32位元組(下面的程式是從main複製出來的，不完整)

//發射端
#include <SPI.h>
#include "RF24.h"

RF24 rf24(8,9); // CE腳, CSN腳
const byte addr[] = "00001";  //傳輸位址
float msg[8] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0}; //共32byte 上限32byte

void setup(){
  if(!rf24.begin()){
    Serial.println("Not responding");
    delay(100);
  }
  rf24.setChannel(83);          // 設定頻道編號
  rf24.openWritingPipe(addr);   // 設定通道位址
  rf24.setPALevel(RF24_PA_MIN); // 設定廣播功率
  rf24.setDataRate(RF24_2MBPS); // 設定傳輸速率
  rf24.stopListening();         // 停止偵聽；設定成發射模式
}

void loop(){
  rf24.write(&msg, sizeof(msg));  // 傳送資料
}

//接收端
#include <SPI.h>
#include "RF24.h"
RF24 rf24(8, 7); // CE腳, CSN腳

const byte addr[] = "00001";
const byte pipe = 1;  // 指定通道編號

float msg[8] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0,}; //共32byte 上限32byte
void setup() {
  Serial.begin(115200);
  while(!rf24.begin()){
    Serial.println("fail");
  }

  rf24.setChannel(83);  // 設定頻道編號
  rf24.setPALevel(RF24_PA_MIN);
  rf24.setDataRate(RF24_2MBPS);
  rf24.openReadingPipe(pipe, addr);  // 開啟通道和位址
  rf24.startListening();  // 開始監聽無線廣播
  Serial.println("nRF24L01 ready!");
}

void loop() {
  if (rf24.available(&pipe)) {
    rf24.read(&msg, sizeof(msg));
    for (auto &i : msg) {
      Serial.print(i);
      Serial.print(' ');
    }Serial.print(pToH(msg[3], Sp));
    Serial.print('\n');
  }
  delay(10);
}

## mpu6050
[lib](https://github.com/Harrysome/MPU6050)
三軸加速度感測器，手刻函式庫，輸出為XYZ傾角，使用I2C協定，addr為0x68

#include <MPU6050.h>
#incldue <Streaming.h>
MPU6050 mpu;
const int add = 0x68;   //the addr of MPU6050
const int sen = 0;   //the sensitivity from 0 ~ 6
void setup(){
	mpu.begin(add, sen);
}
void loop(){
	mpu.read();   //read all the value
  Serial << "( x, y, z) = ( " << mpu.Xaxis() << ", " << mpu.Yaxis() << ", " << mpu.Zaxis() << ")" << endl;

## ms5611
溫度壓力感測器，使用I2C協定，電壓需使用3.3V，addr為0x77

#include "MS5611.h"
MS5611 MS5611(0x77);
void setup(){
  MS5611.begin();
}
/*
  There are 5 oversampling settings, each corresponding to a different amount of milliseconds
  The higher the oversampling, the more accurate the reading will be, however the longer it will take.
  OSR_ULTRA_HIGH -> 8.22 millis
  OSR_HIGH       -> 4.11 millis
  OSR_STANDARD   -> 2.1 millis
  OSR_LOW        -> 1.1 millis
  OSR_ULTRA_LOW  -> 0.5 millis   Default = backwards compatible
*/
void loop(){
	MS5611.setOversampling(OSR_ULTRA_HIGH);
  MS5611.read();
  p1 = MS5611.getPressure();
  t1 = MS5611.getTemperature();
  Serial << "T1 : " << t1 << " P1 : " << p1 << endl;
