Add louder audio to Arduino projects

 Sometimes you want your Arduino-based projects to make a loud noise, much louder than what is possible with a piezo or small speaker. To do this, you need to build a small external circuit based around the popular LM386 speaker amplifier IC. The team at RC Car-Arduino have described a simple circuit to allow you to create loud sounds with your Arduino and said circuit, for example:


Not too bad for a small circuit, that can be easily modified for fun and annoying others. To get started head over to the project page here. And we're on twitter and Google+, so follow us for news and product updates as well.


When creating more complex circuitry such as a multiple-servo controller as described above for your Arduino - consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
