Arduino

使用 Arduino 的 Wolfram 语言设备连接读取数据并将其加入数据仓.

直接从引脚读取：

In[1]:=

X arduino = DeviceOpen["Arduino", "COM26"]

Out[1]=

In[2]:=

X DeviceConfigure[arduino, "Upload"]

In[3]:=

X DatabinAdd[Databin["2anGrs92"], "TemperatureSensor" -> DeviceRead[arduino, "A0"]]

上传自定义 C 代码至 Arduino 以完成更复杂的读取.

准备 Arduino 并上传 Sketch：

In[1]:=

X arduino = DeviceOpen["Arduino", "COM26"]

Out[1]=

In[2]:=

X DeviceConfigure[arduino, "Upload" -> "Functions" -> <|"ReadDistanceSensor" -> ArduinoCode[<|"Code" -> " float readDuration() { float duration; pinMode(9,OUTPUT); digitalWrite(9,LOW); delayMicroseconds(2); digitalWrite(9,HIGH); delayMicroseconds(10); digitalWrite(9,LOW); pinMode(10,INPUT); duration = pulseIn(10,HIGH,16000); return duration*0.01716; } ", "ReturnType" -> Real |>] |>]

执行代码并将结果添加至数据仓：

In[3]:=

X DatabinAdd[Databin["2anGrs92"], "Distance" -> DeviceExecute[arduino, "ReadDistanceSensor"]]
