WALKABLE PIANO
In this project, we use everyday objects from around the house to create a walkable piano.
Hardware setup from the MANY BUTTONS project.
See below for additional parts.

This project uses the same code as Better Piano, but instead of using buttons on the breadboard to play the notes, we are creating our own walkable piano keys that will play sounds when you walk on them.

The only code changes that are required are if you want to add additional keys over and above the four that have already been wired.

Below are step-by-step instructions for building your piano keys and attaching them to the breadboard.  This is what the final circuit on your breadboard should look like -- notice that we'll be leaving the button wired in the circuit in addition to the homemade pressure pad (this is so you can use the button to test the breadboard wiring should you have trouble with your pressure pad):


Parts Required: 

 


Step #1:  Place cardboard centered on tin foil  


Step #2:  Fold and Tape Foil on One Side:

 

Step #3:  Fold and tape foil on other side. Repeat and make another foil/cardboard square

Step #4:  Flip one cardboard/foil square over

 

Step #5:  Tape cardboard strip on one side 

Step #6:  Tape cardboard strip on other side 

Step #7:  Attach other cardboard/foil square to top, with tape. 

Step #8:  Tape wire to one side of pressure pad 


Step #9:  Tape other wire to other side of pressure pad

 
 

Pressure Pad is complete

Step #10:  Attach pad in parallel with button on breadboard

Your homemade piano key should now play a note every time it is pressed...just like our buttons did in previous projects.
