• GitHub: (http://leventerkok.github.com/hArduino)

• Latest Hackage released version: 0.8

Version 0.8, 2013-12-15

• Add support for Piezo speakers
• Add simple musical note playing support, and a jingle-bells playing example. (Not a great rendering, but still recognizable!)

Version 0.7, 2013-11-09

• Export LCD type, for ease of programming
• Added the number guessing game using the OSEpp shield. Thanks to David Palmer for lending me his shield to play with!

Version 0.6, 2013-03-08

• Make hArduino Windows friendly by removing dependence on the unix package. Thanks to Andriy Drozdyuk for pointing out the Windows compilation issue. (Tested on Windows 7.)

Version 0.5, 2013-03-07

• New hardware components supported:
  • Shift-registers
  • Seven-segment displays
  • Servo-motors
• New examples:
  • PulseIn: Demonstrates the use of reading pulses
  • PulseOut: Demonstrates the use of sending pulses
  • Distance: Measure the distance using an HC-SC04 sensor
  • Seven-segment: Display characters on a seven-segment display
  • Servo: Control a servo board
• New functions:
  • pulseIn_hostTiming/pulseOut_hostTiming: Send and receive pulses.
    • NB. These functions use host-timing: watch out for accuracy
  • pulse: Send and receive a digital pulse on a pin.
    • This function is more accurate than the pair above, as it uses a custom Firmata command to measure the pulse. However, you need a custom Firmata version to use this function, as the standard version that ships with Arduino as of March 2013 does not support this functionality yet.
  • time: Measure the time taken by an Arduino action
  • timeOut: Run an action only for the given-time-out

Version 0.4, 2013-03-05

• Bugfix: Remove spurious extra call to user program
• Rework pin assignment logic, making use of analog/digital pins much more clearer.
• Better exception handling
• Remove threadDelay workaround on the Mac. NB. If you are running on OSX, then you need at least GHC 7.6.2!

Version 0.3, 2013-02-10

• Library
  • Add support for pull-up resistors
  • Implement routines for waiting on digital triggers
  • Add support for reading analog values and setting sampling frequency.
  • Add support for LCDs (based on the Hitachi 44780 chip)
  • Better handling for Ctrl-C interrupts
• Examples
  • Counter: Use push buttons to count up and down
  • Analog: Reading analog values
  • LCD: Control an LCD, writing text/glyphs etc

Version 0.2, 2013-01-28

• Library
  • Rewrite the communication engine
  • Digital input/output implementation
• Examples
  • Button: Detecting putton pushes

Version 0.1, 2013-01-14

• Library
  • Initial design
  • Created home page at: http://leventerkok.github.com/hArduino
• Examples
  • Blink: Hello world!
