I would like to read a serial port. I’m going to connect want to connect
my Arduino Uno microcontroller board to the computer via USB. It acts as
a virtual serial port automatically. I can already read with the Arduino
IDE’ s serialterminal.
Processing can also read a serialport from a Arduino.
But now I would like to let Ruby read the virtual serialport and save
the data in a variable. And then do a lots of stuff with it.
Is there a special library or gem for this? I already installed libusb
