Conception de 2 circuits imprimés avec capteurs à effet hall , et une carte arduino , pour un accordéon

OK, I did about 25 (a bit more than half) of the sensors on a 30cm by 3CM PCB. With half done we are using less than half the board space so fitting 49 sensors in to 30Cm shouldn’t be a problem. It is currently late here so I’ll continue this tomorrow. If you can supply the desired spacing between sensors it is easy to move the sensors in to the position you want them (and the leads will allow you to adjust them one way or the other for a short distance as well.)
