PAM8803 audio amplifier module: /* Example: Control a PAM8803 amplifier module from an Arduino board. Created by Diego J. Arevalo, November 20, 2012. Released into the public domain. */ #include <Pam8803.h> int ampVolumeDownPin = 8; // The pin number of the volume down pin. int ampVolumeUpP…

Simpler implementation? getting rid of the if int Pam8803::setVolumeInHalf() { while (_gainSetting <= MAX_GAIN_SETTING/2) volumeUp(); while (_gainSetting >= MAX_GAIN_SETTING/2) volumeDown(); return MAX_GAIN_SETTING/2; } why not a generic percentage function, ? int Pam8803::setVolumePercen…

Updated the library. Now, I will work in improve the volumeUp and Down speed without modify class protocol.

Nice contribution, thanks. By the way I did a quick search on ebay for this type module and found a very nice one that already has terminal connectors and jacks and has an internal voltage regulator so you can power it from either batteries or external DC wall wart type power packs. It also has sol…

Updated the library. Now, I will work in improve the volumeUp and Down speed without modify class protocol. Link to the latest version?

Latest lib could be downloaded from the very first post once you are logged in. About the PAM8803 retrolefty found, the price is great but the size is huge. In my laser gun project size and room are quite important. The one I bought, even If the a few bucks expensive, only measures 2cm x 2xm and cou…

In the library code: void Pam8803::setDigitalVolumeControl(int volumePin){ digitalWrite(volumePin, LOW); delay(30*3.5); digitalWrite(volumePin, HIGH); delay(30); }; What is the purpose of the 3.5 value in the delay statement? Would that cause the floating point math library to be pulled in…

That's why each volume transition requires VUP or VDOWN pin remais active low for 3.5 clock cycles. I did not floating point lib would be included. I will put 105 instead. Thanks for the suggestion.

This library and module work nicely. However, I'm using it for a clock like application for late night use, and even at the lowest setting pam8803.setVolume(0); it's still far too loud... It's definitely adjusting by setVolume. setVolume(100) is very loud, and setVolume(10) is modest, but even s…

on this module: http://www.ebay.com/itm/2-2W-4O-PAM8803-Class-D-Audio-Amplifier-Board-Simple-/350604041652?pt=US_Home_Audio_Amplifiers_Preamps&hash=item51a1a11db4 There's no explicit access to the reset RST pin as far as I can see, which pam8803.reset() invokes. It's apparently pin 15 on the main …
