I was not sure if placing more condenser in parallel was wrong for the circuit.
It is not "wrong" for the circuit operation by any means, but you do have to be ever-so-slightly cautious that the power supply can manage both the inrush current of a large combined capacitance and the nature of the load combining the capacitance plus the inductance of the connecting wires - which may be quite significant.
I know, so I will use a 70 ampere power supply, it should work well!
A fuse in each branch of the wiring would be in order then, not to protect the electronics, but to protect against the wiring catching fire.
you mean to place a fuse instead of condensers
put a small one between your power supply and the Arduino side of things.
