Hi, I'm beginner and I started my first project.
I want to make LEDs sync to music by using the audio from a mp3. I used a TIP31C transistor and connected
the positive of the audio wire to the base
the ground from the battery and the ground of the audio wire to the emitter
the negative of an LED to the collector,
and the positive of the LED to the battery.
The circuit works but the LEDs only respond to the loud parts of the song, and I have my computer speakers set to earsplitting maximum.
The main problem is, I want this to work on an mp3 but even my computer speakers on maximum isn't powerful enough to make the LEDs respond to most of the song. What I want to know is what should I do to fix this problem? Do I need a different transistor? So far, I'm testing this with a 6v battery and 1 led.
