Sound Servo (PC Speaker)
icon to add the control to your project
Control servos by the PC speaker sound source of your computer's soundcard - any audio played through the default PC Speaker device can control servos. You can control many servos with this control by using the Configure option. Specify the scalar to increase the dynamic range of the audio in relation to the position of the servo. Don't worry if that sounds confusing, play with it and see what you get.
