How a Transistor works

[95Rafao]

I want to do it with 2 leds. The transistor is the same?

@95Rafao Din't know for sure... you'll have to try it... but, higher consumption needs different (power)transistor.

It's very nice. But an educational addition would be to show the schematic representations as you go, and then the completed schematic.

I subscribed immediately.

wow you should be a teacher!!!!

short and sweet ... nice video ... but let say you want some sound reactive led where would you connect the + and the - on that circuit ..thanks

@GHOSTTOYS ;-?  :-?? :D

@GHOSTTOYS if you want it to be sound reactive you would connect the + of the audio signal from sound card to the base of the transistor and the ground of the signal to battery ground :)

@GHOSTTOYS you mean with a microphone instead of his fingers?

[GHOSTTOYS]

@AcousticBruce i think , yes .. but the finger is a small signal and microphone got more .. i have search every where for a simple sound reactive circuit , the smallest possible but nothing efficient and i dont know enought in electronic to etch my hown circuit from scratch , i was needing that circuit for a psp ... or a nintendo ds and all the circuit i tryed left the led on and pulsate it but me i want it to be off and then activated (no white noise reaction)
