I show you how to
I show you how to make VU METER LED 20 levels BAR graph mode without IC.
In this video I use BC547 Transistors. You can use any other TUN (Transistor Universal NPN), but you have pay attention into the Transistor pins (Emitter Base Collector).
- For the genuine BC547 NPN Transistor pins structure: pin 1 is Collector, pin 2 is Base, pin 3 is Emitter, (CBE).
- For the genuine A1015 PNP Transistor pins structure: pin 1 is Emitter, pin 2 is Collector, pin 3 is Base, (ECB).
- For the genuine C1815 or C945 NPN Transistor pins structure: pin 1 is Emitter, pin 2 is Collector, pin 3 is Base, (ECB).
- For the genuine FCS9013 (C9013) or FCS9014 (C9014) NPN Transistor pins structure: pin 1 is Emitter, pin 2 is Base, pin 3 is Collector, (EBC).
