Hi all, i m trying to build a circuit to light up LED with an MP3 player. I mean LED will blink or light with sound signals. It goes fine. But LED is not so bright. I. Think i need to amplify the current using a transistor. But i dont know much about them. So plz guide me what transistor or some thing other should i use. I want it to be easy and simple.
