WEB-ENABLED BACKYARD ARTILLERY

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 :)

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 :https://www.instructables.com/id/LED-throwie-CANNON/

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
 

the software comes from another one of my previous instructables found here: https://www.instructables.com/id/How-to-use-Google-Sites-to-control-a-Arduino/
