A simple way to send serial data to Arduino. I'm sending Data to a Servo Motor...

;; Setup TERMINAL (Mac)
;; stty -f /dev/dev/cu.usbmodem1401 9600 raw


(defparameter *arduino*
  (open "/dev/cu.usbmodem1401"
        :direction :output
        :if-exists :append
        :element-type '(unsigned-byte 8)))

;;Function
(defun send-byte (n)
          (uiop:run-program
           (format nil "printf '%b' \"\\x~2,'0X\" > /dev/cu.usbmodem1401"
                   n)))


;;Test
(loop repeat 20
        do (send-byte (random 100))
        do (sleep 1))

I've only heard of Arduino, but what is a use case for Arduino with opm?
Thanks,

For a project, I control servos and relays (as an instrument) via Arduino using LISP — although, of course, the same thing could also be done in MaxMSP (or with other programming environments). I’m a bit familiar with LISP, so I can use it to program structures, timing, rhythms, etc. — or, as in this particular case, a “3D sample space.” I read the elements of this space using different algorithms (boustrophedon, brownian bridge, kNN), essentially generating reading paths, and then send the resulting data/material to the Arduino to control the relays and motors.
