Using this Code

Gaugette.ino is an Ardiuno sketch that uses a simple serial command language to control one or more analog gauges. The following ruby sample code sends command sequences to the attached Arduino from a host computer. The clients directory includes a complete example that showns bandwidth in and out from a pfSense firewall on two analog gauges.

require 'gaugette'

# open serial connection to Arduino running gaugette.ino
@gaugette = Gaugette.new("/dev/tty.usbmodem24411")

# zero and configure each motor
[0,1].each {|i| @gaugette.zero(i)}

# move motors in sync
v = 0
6.times do |i|
  @gaugette.set(1, v)
  @gaugette.set(0, v)
  sleep 1
  v = 1-v
end
