Hi,

after loads of searching through the forums i can't seem to find anything that fully explain how to achieve this? Ive saw loads of people doing it so i know it can be done such as this video..

And lots of other examples, but I'm not sure where to start?

I have an uno will this work?

I purchased a solenoid to get going as well as a midi shield if needed but not quite sure how to get everything going in-between?

Any help would be great! thanks!
