Electrical Connections

The SoundBytes module needs 5-24 volts of clean direct current (DC) power to operate.  Connect the white wire to GND to activate the sound.  Leave the white wire disconnected when not in use.

Red Wire = 5V to 24V
Black Wire = GND
White Wire = GND to activate

The volume can be adjusted by using a small screwdriver to turn the white, square potentiometer on the PCB.

Here is an example showing the SoundBytes module connected to a toggle switch:
