I am making a TARDIS (long story!) and I have a key fob which generates the sound of the TARDIS materialising. Basically, a circuit board makes a sound come out of a tiny little speaker.
I've taken the thing apart and connected the two speaker wires to a slightly bigger speaker (3W, 4ohm) and it makes a quiet noise. I've tried to connect the same speaker wires to the audio input of the LM386 module, and the bigger speaker to its output. Now I get no sound.
I know the power is working to the LM386 module because the little D1 LED is lit. What am I doing wrong?
Thanks much.
