Hi, I'm finishing a project on a Midi control pedalboard. Feed the pedalboard with a 1700mAh transformer and in turn this transformer feeds some of the effects it controls. The sum of the consumption of everything does not reach even 1400mAh.
It turns out that when I connect the Arduino the effects connected to the same transformer make noise.
I changed the transformer, reduced the load and continue to produce alike, so I think it is the Arduino and connected components.
Anyone know if there is a filter that eliminates these noises?
Thanks and regards.
