Step motors

Alejo Duque

step motor meets the ArtBus

Using the ArtBus, a micro-controller designed at the Art Institute of Chicago (in development), for controlling a step motor. The project began during the FACE workshop, it will be hopefully used to control a video camera (or a microphone, or anything) remotely via an IRC (Internet Relay Chat) bot. (more soon) /ad

software

In this case we use python code to send the messages to the ArtBus but is possible to use puredata or any other software that can talk to the serial port. Robb coded an OSC interface that serves as a mediator to allow comminication via the OpenSoundControl protocol. The code will be added to this page as soon as is properly tested.

Here, a little video clip that shows the interaction flow from irc chat lines (!east or !west) to python commands sent via serial communication to the ArtBus (or arduino, or whatever microcontroller board)

code

The code below was tailored by favian voegeli with the help and comments of alejo duque (step motor patterns) based on code and ideas shared with robert drinkwater. It is a base example. The other half is the supybot configuration file that will allow the irc bot to send messages to the serial port.

#
# Default value: supybot
###
supybot.nick: HalfBrother

###
# Determines what alternative nicks will be used if the primary nick
# (supybot.nick) isn't available. A %s in this nick is replaced by the

# are used, the supybot.nick will be perturbed appropriately until an
# unused nick is found.
#
# Default value: %s` %s_

###
# Determines what servers the bot will connect to for goto10. Each will

###
# Determines the absolute maximum length of the bot's reply -- no reply
# will be passed through the bot with a length greater than this.
#
# Default value: 131072
###
supybot.reply.maximumLength: 131072

###
# Determines whether the bot will break up long messages into chunks and

#
# Default value: True
###
supybot.reply.mores: True

###
# Determines what the maximum number of chunks (for use with the 'more'
# command) will be.
#
# Default value: 50
###
supybot.reply.mores.maximum: 50

###
# Determines how long individual chunks will be. If set to 0, uses our
# super-tweaked, get-the-most-out-of-an-individual-message default.
#
# Default value: 0
###
supybot.reply.mores.length: 0

###
# Determines how many mores will be sent instantly (i.e., without the
# use of the more command, immediately when they are formed). Defaults
# to 1, which means that a more command will be required for all but the
# first chunk.
#
# Default value: 1
###
supybot.reply.mores.instant: 1

###
# Determines whether the bot will send multi-message replies in a single
# message or in multiple messages. For safety purposes (so the bot is
# less likely to flood) it will normally send everything in a single
# message, using mores if necessary.
#
# Default value: True
###
supybot.reply.oneToOne: True

###
# Determines whether the bot will reply with an error message when it is
# addressed but not given a valid command. If this value is False, the
# bot will remain silent, as long as no other plugins override the
# normal behavior.
#
# Default value: True
###
supybot.reply.whenNotCommand: True

###
# Determines whether error messages that result from bugs in the bot
# will show a detailed error message (the uncaught exception) or a
# generic error message.
#
# Default value: False
###
supybot.reply.error.detailed: False

###
# Determines whether the bot will send error messages to users in
# private. You might want to do this in order to keep channel traffic to
# minimum. This can be used in combination with
# supybot.reply.error.withNotice.
#
# Default value: False
###
supybot.reply.error.inPrivate: False

###
# Determines whether the bot will send error messages to users via
# NOTICE instead of PRIVMSG. You might want to do this so users can
# ignore NOTICEs from the bot and not have to see error messages; or you
# might want to use it in combination with supybot.reply.errorInPrivate
# so private errors don't open a query window in most IRC clients.
#
# Default value: False
###
supybot.reply.error.withNotice: False

###
# Determines whether the bot will send an error message to users who
# attempt to call a command for which they do not have the necessary
# capability. You may wish to make this True if you don't want users to
# understand the underlying security system preventing them from running
# certain commands.
#
# Default value: False
###
supybot.reply.error.noCapability: False

###
# Determines whether the bot will reply privately when replying in a
# channel, rather than replying to the whole channel.
#
# Default value: False
###
supybot.reply.inPrivate: False

###
# Determines whether the bot will reply with a notice when replying in a
# channel, rather than replying with a privmsg as normal.
#
# Default value: False
###
supybot.reply.withNotice: False

###
# Determines whether the bot will reply with a notice when it is sending
# a private message, in order not to open a /query window in clients.
# This can be overridden by individual users via the user configuration
# variable reply.withNoticeWhenPrivate.
#
# Default value: False
###
supybot.reply.withNoticeWhenPrivate: False

###
# Determines whether the bot will always prefix the user's nick to its
# reply to that user's command.
#
# Default value: True
###
supybot.reply.withNickPrefix: True

###
# Determines whether the bot should attempt to reply to all messages
# even if they don't address it (either via its nick or a prefix
# character). If you set this to True, you almost certainly want to set
# supybot.reply.whenNotCommand to False.
#
# Default value: False
###
supybot.reply.whenNotAddressed: False

###
# Determines whether the bot will allow you to send channel-related
# commands outside of that channel. Sometimes people find it confusing
# if a channel-related command (like Filter.outfilter) changes the
# behavior of the channel but was sent outside the channel itself.
#
# Default value: False
###
supybot.reply.requireChannelCommandsToBeSentInChannel: False

###
# Supybot normally replies with the full help whenever a user misuses a
# command. If this value is set to True, the bot will only reply with
# the syntax of the command (the first line of the help) rather than the
# full help.
#
# Default value: False
###
supybot.reply.showSimpleSyntax: False

###
# Determines what prefix characters the bot will reply to. A prefix
# character is a single character that the bot will use to determine
# what messages are addressed to it; when there are no prefix characters
# set, it just uses its nick. Each character in this string is
# interpreted individually; you can have multiple prefix chars
# simultaneously, and if any one of them is used as a prefix the bot
# will assume it is being addressed.
#
# Default value: 
###
supybot.reply.whenAddressedBy.chars: !

###
# Determines what strings the bot will reply to when they are at the
# beginning of the message. Whereas prefix.chars can only be one
# character (although there can be many of them), this variable is a
# space-separated list of strings, so you can set something like '@@ ??'
# and the bot will reply when a message is prefixed by either @@ or ??.
#
# Default value:  
###
supybot.reply.whenAddressedBy.strings:  

###
# Determines whether the bot will reply when people address it by its
# nick, rather than with a prefix character.
#
# Default value: True
###
supybot.reply.whenAddressedBy.nick: True

###
# Determines whether the bot will reply when people address it by its
# nick at the end of the message, rather than at the beginning.
#
# Default value: False
###
supybot.reply.whenAddressedBy.nick.atEnd: False

###
# Determines what extra nicks the bot will always respond to when
# addressed by, even if its current nick is something else.
#
# Default value:  
###
supybot.reply.whenAddressedBy.nicks:  

###
# Determines whether the bot will unidentify someone when that person
# changes his or her nick. Setting this to True will cause the bot to
# track such changes. It defaults to False for a little greater
# security.
#
# Default value: False
###
supybot.followIdentificationThroughNickChanges: False

###
# Determines whether the bot will always join a channel when it's
# invited. If this value is False, the bot will only join a channel if
# the user inviting it has the 'admin' capability (or if it's explicitly
# told to join the channel using the Admin.join command)
#
# Default value: False
###
supybot.alwaysJoinOnInvite: False

###
# Determines what message the bot replies with when a command succeeded.
# If this configuration variable is empty, no success message will be
# sent.
###
supybot.replies.success: done.

###
# Determines what error message the bot gives when it wants to be
# ambiguous.
###
supybot.replies.error: An error has occurred and has been logged. Please\
                       contact this bot's administrator for more\
                       information.

###
# Determines what message the bot replies with when someone tries to use
# a command that requires being identified or having a password and
# neither credential is correct.
###
supybot.replies.incorrectAuthentication: Your hostmask doesn't match or your\
                                         password is wrong.

###
# Determines what error message the bot replies with when someone tries
# to accessing some information on a user the bot doesn't know about.
###
supybot.replies.noUser: I can't find %s in my user database. If you didn't\
                        give a user name, then I might not know what your\
                        user is, and you'll need to identify before this\
                        command might work.

###
# Determines what error message the bot replies with when someone tries
# to do something that requires them to be registered but they're not
# currently recognized.
###
supybot.replies.notRegistered: You must be registered to use this command.\
                               If you are already registered, you must\
                               either identify (using the identify command)\
                               or add a hostmask matching your current\
                               hostmask (using the "hostmask add" command).

###
# Determines what error message is given when the bot is telling someone
# they aren't cool enough to use the command they tried to use.
###
supybot.replies.noCapability: You don't have the %s capability. If you think\
                              that you should have this capability, be sure\
                              that you are identified before trying again.\
                              The 'whoami' command can tell you if you're\
                              identified.

###
# Determines what generic error message is given when the bot is telling
# someone that they aren't cool enough to use the command they tried to
# use, and the author of the code calling errorNoCapability didn't
# provide an explicit capability for whatever reason.
###
supybot.replies.genericNoCapability: You're missing some capability you\
                                     need. This could be because you\
                                     actually possess the anti-capability\
                                     for the capability that's required of\
                                     you, or because the channel provides\
                                     that anti-capability by default, or\
                                     because the global capabilities include\
                                     that anti-capability. Or, it could be\
                                     because the channel or\
                                     supybot.capabilities.default is set to\
                                     False, meaning that no commands are\
                                     allowed unless explicitly in your\
                                     capabilities. Either way, you can't do\
                                     what you want to do.

###
# Determines what error messages the bot sends to people who try to do
# things in a channel that really should be done in private.
###
supybot.replies.requiresPrivacy: That operation cannot be done in a channel.

###
# Determines what message the bot sends when it thinks you've
# encountered a bug that the developers don't know about.
###
supybot.replies.possibleBug: This may be a bug. If you think it is, please\

###
# Supybot allows you to specify what brackets are used for your nested
