Hey guys,
so I have this "instrucables.com" schematic from a DIY project and SChematic1 represents that. but I was wondering...
Exactly what is biasing this transistor? (im pretty sure its Emitter Biased)
And Should there be a 1k transistor in the Area of Question?
** I didn't anticipate my computer would take a revers picture of it. but you get the idea. 10k on the base, led with 330 on it. im wondering about the circle. should there be a resistor on it and why?
Edit: I attached another picture. will this work for my relay board? the female socket is going to be old dead Christmas lights. I didn't quite understand why all the loads would be connected. does this make the difference of potential needed
