AmbientOrb
Ruby code to interface with ambientdevices Ambient Orb. Only supports the serial interface as ambientdevices' service no longer exists.
require 'ambient-orb'
# device is automatically detected on OS X
orb = AmbientOrb.new
# a device can be passed manually
#orb = AmbientOrb.new(:device => '/dev/ttyS0')
# a logger can also be passed
#orb = AmbientOrb.new(:logger => Logger.new(STDOUT))
#orb.logger.level = Logger::DEBUG

endHardware Setup
This gem has been tested with two hardware setups.
Arduino Uno R3
Using the Arduino Uno R3 as a USB to serial TTL converter. The R3 uses an atmega16u2 chip.
- Connect Pin 5 (RX) on the Orb to Pin 0 (RX) on the Arduino.
- Connect Pin 6 (TX) on the Orb to Pin 1 (TX) on the Arduino.
- Connect RESET to GND on the Arduino.
FT232R USB to 5V TTL level UART cable
Using the EZSync FTDI chip usb to 5v TTL UART serial cable, connector end, 1.5m, TTL-232R-5V compatible cable. This cable uses the FT232R chip.
- Connect Pin 5 (RX) on the Orb to Pin 4 (TXD, Orange) on the cable.
- Connect Pin 6 (TX) on the Orb to Pin 5 (RXD, Yellow) on the cable.
