howdy everyone! this instructable is actually the culmination of many past projects of mine, however they have all been used together to do something really cool! basically its a cannon that you can control over the web through a google site apps script, so without further ado, let us begin BTW Please watch the video, it explains it all :)
Step 1: the cannon
in order to get the best result ive designed a custom valve system that is pneumatically actuated the details to the construction of this cannon can be found in this other instructable of mine :http://www.instructables.com/id/LED-throwie-CANNON/
Step 2: the control electronics
ok, so the electronics were recycled from another project of mine, i was building a light sequencer for the holidays to out do the neighbors in Christmas decorations but it worked fine for my purpose of switching a solenoid valve heres a video if you curious to know what this thing is capable of.
Step 3: the software
the software comes from another one of my previous instructables found here: http://www.instructables.com/id/How-to-use-Google-Sites-to-control-a-Arduino/
