Audio Amplifier Appmod
|
| |
Description:
The BASIC Stamp microcontroller has two commands to generate sounds: DTMFOUT and FREQOUT. To make the most of these commands an audio amplifier circuit should be used. The Audio Amplifier AppMod makes it easy and is a great way to add sound output to your BOE-Bot robot or Toddler robot.
Features:
- 125 milliwatt amplifier
- Adjustable volume control
- Built-in speaker
- Selectable external speaker connection
Parallax standard AppMod format, so it plugs right in to a Board of Education carrier board, Super Carrier Board, and Activity Board. The Audio Amplifier AppMod employs an industry-standard LM386 audio amplifier. Raw audio output is taken from BASIC Stamp pin 10 and filtered prior to amplification; this converts the pulse-width modulation output of the BASIC Stamp module to sinusoidal waves for the best audio quality. The amplified signal is fed to an onboard 8 ohm speaker. You may connect an external speaker for even better quality sound and volume.
