因為作品看起來像四個MAN靠在一起，所以命名為 "靠杯"

有沒有靠妖系列 ?

NVIDIA在今年Siggraph推出一款概念AR眼鏡，視野範圍是HOLOLENS的兩倍，可參考一下這篇文章。

和一般的垃圾車很像

不過這是海邊專用 ‼️

可以將沙子和塑膠垃圾分離

快速的將垃圾撿起 ?

還給大家乾淨的戲水空間 ?

應該是把沙子和其他東西分離，包括但不僅限於塑膠袋、瓶子、貝殼、海灘生物...

嗯~~搞了一整天, 都還以為我寫錯甚麼東西, 原來是DFRobot SIM-7000C自己的library把APN寫死了, 害我擔心得要命!

搞定啦! 可以用中華電信NB-IoT上傳數據到ThingSpeak了

最近因為產學合作專案的需求, 正在摸NB-IoT, 所以上網買了一個這玩意 :
https://www.dfrobot.com/product-1701.html

然後辦了一張中華電信的NB-IoT SIM Card, 透過Arduino Uno來寫程式試試. 不過...似乎並不是很順利, 一直卡在沒辦法Attach service :

# include <Wire.h>
#include <DFRobot_SIM7000.h>

# define PIN_TX 7
#define PIN_RX 8
SoftwareSerial mySerial(PIN_RX,PIN_TX);
DFRobot_SIM7000 sim7000;
static char buff[350];

void setup(){
int signalStrength,dataNum;
Serial.begin(115200);

mySerial.begin(19200);

sim7000.begin(mySerial);
sim7000.turnOFF();
delay(5000);
Serial.println(F("Turn ON SIM7000......"));
if(sim7000.turnON()){ //Turn ON SIM7000
Serial.println(F("Turn ON !"));
}
Serial.println(F("Set baud rate......"));
if(sim7000.setBaudRate(19200)){ //Set baud rate from 115200 to 19200
Serial.println(F("Set baud rate:19200"));
}else{
Serial.println(F("Faile to set baud rate"));
while(1);
}
Serial.println(F("Check SIM card......"));
if(sim7000.checkSIMStatus()){ //Check SIM card
Serial.println(F("SIM card READY"));
}else{
Serial.println(F("SIM card ERROR"));
while(1);
}
delay(500);
Serial.println(F("Set net mod......"));
if(sim7000.setNetMode(NB)){ //Set net mod NB-IOT ,Please make sure your SIM card is NB-IOT card or you should choose GPRS mode
Serial.println(F("Set NB-IOT mode"));
}else{
Serial.println(F("Fail to set mode"));
}

//mySerial.print(F("AT\r\n")); delay(500);
//mySerial.print(F("AT+CNBP=0000000000000080\r\n")); delay(500);

Serial.println(F("Get signal quality......"));
delay(500);
signalStrength=sim7000.checkSignalQuality(); //Check signal quality from (0-30)
Serial.print(F("signalStrength ="));
Serial.println(signalStrength);
delay(500);
Serial.println(F("Attaching service......"));
if(sim7000.attacthService()){ //Open the connection
Serial.println(F("Attach service"));
}else{
Serial.println(F("Fail to Attach service"));
while(1);
}
delay(200);
Serial.println(F("Connecting......"));
if(sim7000.openNetwork(TCP," www.taobao.com ",80)){ //Start Up TCP or UDP Connection
Serial.println(F("Connect OK"));
}else{
Serial.println(F("Fail to connect"));
while(1);
}
sim7000.send("HEAD/HTTP/1.1\r\nHost: www.taobao.com \r\nConnection:keep-alive\r\n\r\n"); //Send Data Through TCP or UDP Connection
dataNum=sim7000.recv(buff,350,0); //Receive data
Serial.print(F("dataNum="));
Serial.println(dataNum);
Serial.println(buff);
delay(500);
if(sim7000.closeNetwork()){ //End the connection
Serial.println(F("Close connection"));
}else{
Serial.println(F("Fail to close connection"));
}
delay(2000);
sim7000.turnOFF(); //Turn OFF SIM7000
}
