Hey everyone, I have a 555 timer hooked up to an 8 ohm speaker and I adjust it with a variable potentiometer. I get different tones depending on how I increase or decrease resistance. Here is my question: Since the only component driving the speaker is the 555 chip, then if I had the chip (output pin #3) control an NPN transistor and the transistor control the speaker will I get more power to the speaker and make it much louder ?
