MC34063A Up, Step Down to a simple handy converter IC − DCDC mc3406a calculation tool I used had a problem with this program I have shared this search is doing a more detailed calculation of the variations of the circuit to be used can be selected fast diode,
Vu-meter Schaltung mit LM3914
VU-Meter-Schaltung linker und rechter Kanal als der zweite Abschnitt der Schaltungen besteht 6 10 s LED-Anzeige verwendet schließlich jedes Display 10 LEDs, wo die pro Kanal 60 LEDs mit insgesamt 120 LEDs gleichzeitig pro Kanal verwendet werden, 6 LM3914 wird verwendet, um die Integration a eine synchron mit den Arbeiten, aber auf dem ersten Audiosignal -Eingabe der Schaltung 1k (Anwendung verwendet 3.3K) befindet, indem sie mit einem Multimeter Messung notwendig Potenziometer einzustellen
