Bot-Logic 1Watt Audio Amp

Make your next robot speak! Or sing! Or recite Shakespeare!

The BOBot-Logic ButtonsT-LOGIC DUE Has a 1-watt audio amplifier that, when connected to a speaker, utilizes the DAC in the Arduino DUE to play audio files from the SD card.

When using the BOT-LOGIC Due with a the Arduino Mega, the audio input can be connected to a PWM output.

The audio amplfier is powered from the 5V Arduino supply and can drive an 8-ohm speaker connected to J2. Notice the location of the audio volume control on the right between the LCD and the user-programmable buttons. The audio circuit can be seen on the left on the opposite side of the board from the volume control.
