I got a small loudspeaker and tried connecting it to the output of a 555 (pin 3), but I am not sure which pin of the speaker to use (1, 2, 3 or 4).

I was just using this old drawing to show that the speaker was connected to a 555, but I am taking your advice, thanks.I had already suggested that here.
Volume control 555-speaker circuit?
I don't know if the OP decided to ignore the advice or is using an old drawing.
As Wookie says, you need to isolate the DC component, it is nothing but bad for the speaker.
The 555 is not an audio power amplifier. Its max allowed output current is only 200mA.I was using Yenka to test the circuit and tried connecting the speaker to the 555 with the capacitor like you said, but the 555 blew up and the following message was displayed: The power dissipated was 1.29W. The maximum rating is 600 mW. Why is this?
