Collect Data from Arduino Yun

Create a channel for publishing data from an Arduino Yun device and start listening on the channel.

In[1]:=

channel = CreateChannel["yun", Permissions -> "Public"]

Out[1]=

In[2]:=

listener = ChannelListen[channel]

Out[2]=

Open an Arduino Yun device.

In[3]:=

yun = DeviceOpen[ "Arduino", {"/dev/tty.usbmodem1421", "BoardType" -> "Yun"}]

Out[3]=

Configure the device to send values of the analog pins A0 through A2 to the channel every 0.5 second.

In[4]:=

DeviceConfigure[yun, "Upload" -> {"BootFunction" -> <|"Code" -> "ChannelSend", "Pins" -> {"A0", "A1", "A2"}, "Scheduling" -> 0.5, "Channel" -> channel|>}]

Out[4]=

Close the device, unplug it, attach an accelerometer to the analog pins, and put the Yun out in the field.

In[5]:=

DeviceClose[yun]

Visualize the data as it comes in.

In[6]:=

Dynamic[ListLinePlot[ ToExpression /@ Reverse[Take[Reverse[#["Values"]], UpTo[100]]], PlotRange -> {0, 5}] & /@ listener["TimeSeries"]]
