Arduino

Use the Wolfram Language Device Connection for Arduino to read data and add it to a databin.

Read directly from the pins:

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"]]

Upload custom C code to the Arduino to take more sophisticated readings.

Prepare the Arduino and upload a 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 |>] |>]

Execute the code and add the results to a databin:

In[3]:=

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