Step 4: Amplifier Socket¶
It's nice that we have this fancy, filtered signal now, but that's not going to do us a whole lot of good if we can't hear it. The signal we have is weak!
The LM386 is a nice, simple amplifier that will not only make your signal bigger, but also give it more POWER, so that by the time the signal makes it to the speaker or the headphones, you can actually hear it!
- Soldering iron
- Electrical tape
- 1 x 4-pin DIP socket
Find the footprint for U6.
Tape it into place as with previous sockets and solder into place.
