Good evening Peter, good old gray! , I’ll look at your work, if you have to buy other hall effect sensors, connectors dupont no problem! I bought a lot of things (200 €) by counting the arduino card, magnets in Germany at super magnete, 200 sensors in China I used about 55, wire, connectors for arduino in China! . small circuit boards to double-sided! It is not a problem however to buy other sensors with longer legs I could actually orient them a little more easily. How many wires will be connected to the arduino card? 20? there are also some that will be looped between the printed circuit of the right hand and the printed circuit of the left hand: 22 24 26 28 30 32 Thank you for your work it’s great!
For fun !
For information here is the table of correspondence between a note of music and the midi coding which is affected to him. The correspondence with the diagram of Tom scarff.
For the keyboard of the right hand:
From (Mi1) E1 to (Mi5) E5 are midi codes (28 to 76), sensors SW 50 to SW 98 (tom scarff)
For the keyboard of the left hand:
From (Sib1) Bb1 to (sib5) Bb5 are midi codes (34 to 82), sensors SW 1- SW 49. This makes it possible to understand how the circuit boards will be positioned, from low to high, from top to bottom for the keyboard of the right hand and from low to high, from the bottom to the top for the keyboard of the left hand. . In addition, the push buttons
will allow to go down or up the octaves
hihihi !
