Question

So, I\'m in a bit over my head, and I feel like I\'m very close to a solution, but it\'s just not working quite yet. Here\'s my situation:

I\'m working with an Ardui

Answer 1

A one-liner Something that works really well for datalogging, and acting on data:

Summary

• monitoring: the arduino output can trigger actions on the computer
• data-logging: it simultaneously save that streaming data to a file
• notchecked? sending-messages: I haven't tried sending data yet to the arduino, but see the second example, might be able to send a message to the serial port via some cmdline util.

the following timestamps and sends to stdout

cat /dev/cu.usbmodem1421 | awk '{ for (i=0; i

Sample Output:

This method can even be adapted to monitor and act upon the data in real time:

cat /dev/cu.usbmodem1421 | awk '{ for (i=0; i
