I haven’t been able to output yet, but I am not sure that the problem is with the code. Should it work with no action at all from my end? In other words, should I be able to push the button on the bar code reader and see the output in the serial monitor? When I attempt to view the serial monitor I receive the following:
ben-theyes-mbp:library bentheye$ spark serial list
Found 1 core(s) connected via serial:
1: /dev/cu.usbmodem621
ben-theyes-mbp:library bentheye$ spark serial monitor
Opening serial monitor for com port: "/dev/cu.usbmodem621"
