Update:

This mini robot tank is fully assembled. Keyestudio sent me the sample code for an earlier version (version 1), not the current version (version 2), which I have attached here (the code is open and free to use from Keyestudio for similar projectsm, but I recommend the Mini Robot Tank V2 project kit).

At the moment, I'm busy on other projects, still hoping to get the V2 code, and need to buy the batteries; but hope to this this up and running in the not-to-distant future and sending data via MQTT and Node-RED, as "just another node on the network".

Libravatar::URL(3pm)					User Contributed Perl Documentation				      Libravatar::URL(3pm)

NAME
Libravatar::URL - Make URLs for Libravatars from an email address SYNOPSIS
use Libravatar::URL; my $url = libravatar_url( email => 'larry@example.org' ); DESCRIPTION
See <http://www.libravatar.org> for more information. Functions libravatar_url # By email my $url = libravatar_url( email => $email, %options ); # By OpenID my $url = libravatar_url( openid => $openid, %options ); Constructs a URL to fetch the Libravatar for the given $email address or $openid URL. %options are optional. "libravatar_url" will accept all the options of "gravatar_url" in Gravatar::URL except for "rating" and "border". The available options are... size Specifies the desired width and height of the avatar (they are square). Valid values are from 1 to 512 inclusive. Any size other than 80 may cause the original image to be downsampled using bicubic resampling before output. size => 40, # 40 x 40 image default The url to use if the user has no avatar. default => "http://www.example.org/nobody.jpg" Relative URLs will be relative to the base (ie. libravatar.org), not your web site. Libravatar defines special values that you may use as a default to produce dynamic default images. These are "identicon", "monsterid", "wavatar" and "retro". "404" will cause the URL to return an HTTP 404 "Not Found" error instead and "mm" will display the same "mystery man" image for everybody. See <http://www.libravatar.org/api> for more info. If omitted, Libravatar will serve up their default image, the orange butterfly. base This is the URL of the location of the Libravatar server you wish to grab avatars from. Defaults to <http://cdn.libravatar.org/avatar/> for HTTP and <https://seccdn.libravatar.org/avatar/> for HTTPS. short_keys If true, use short key names when constructing the URL. "s" instead of "size", "d" instead of "default" and so on. short_keys defaults to true. https If true, serve avatars over HTTPS instead of HTTP. You should select this option if your site is served over HTTPS to avoid browser warnings about the presence of insecure content. https defaults to false. LICENSE
