You can do it with a makey makey and some aluminium foil.

We updated the description, but here is the guide for making your own! makeymakey.com/blogs/how-to-instructions/oversized-and-portable-floor-piano

@@Makeymakey How do you wire the cables to the Makey Makey board? I don´t see that in any video. Thanks

@@sebastian.arancibia The wiring is on this page and there are two graphics that show what piano keys will go to what Makey Makey inputs. makeymakey.com/blogs/how-to-instructions/oversized-and-portable-floor-piano

Are you using an external speaker? What OS and browser are you using and experiencing latency?

Oh no I'm not using it yet, I want to buy a Makey Makey for a similar use to a Foot Piano, so I was checking your videos and I just noticed the latency in this one..I would by the way use Windows 10 x64

And yes with an external speaker 😊

@@chiarabolignari5603 Oh gotcha ! The slight latency here is we were in a school using school wifi, using an external speaker and coded our piano in Scratch. Our plug and play apps usually don't have latency.

@@Makeymakey cool, thanx a lot for the answer 🙃

Hey there! There are 6 inputs on the front and 12 more inputs on the back. If you flip over the board, there are black headers, the small white wires that come in your kit are how you access those. Here is a full tutorial: makeymakey.com/blogs/how-to-instructions/back-of-the-board-tutorial

The tutorial in the description also shows how to access this.

@@Makeymakey oh, it's true. I'm feeling so dum kkkk. Thanks so much.

@@aplicarciencias Oh no! Don't feel like that! We noticed a lot of people don't seem to realize they can access the back, that's why we made new backpacks to make the back of the board more accessible! makeymakey.com/products/makey-makey-bananaversary-backpack-bundle
