Testing a simple LM386 amplifier (not very loud) #dogilab
This is a low-power audio amplifier test using the LM386. The audio input came from a headphone cable taken from a small radio, and the output was connected to a buzzer used as a speaker substitute. The circuit works, but the sound level is low. Most likely because the LM386 is a low-power amplifier and the buzzer is not an ideal speaker load ...
