Web23 de mar. de 2024 · Sorted by: 1. To effectively drive a speaker from an Arduino you need an amplifier. The good ol' LM386 is a common choice for this (readily available and cheap, though not recommended for battery based projects). While it is possible to drive a speaker directly it's not recommended. Not only is it very quiet, but also it can damage the IO pin. Web1 de mar. de 2009 · Mar 1, 2009. #18. The datasheet shows that an LM386 with a 12V supply and an 8 ohm speaker has an output at clipping of 6.5V p-p which is 0.66W. Then it dissipates 0.82W of heat which is a lot for the small DIL-8 pins case. It will be pretty hot. With a 9V supply the output at clipping is 6V p-p which is 0.56W.
