The EMGRobotics A2SCB can be controlled by simply playing a WAV file. The following WAV files were created for the STEMbot1 project using the EMGRobotics RC Servo Controller Android application. Simply use the on-screen sliders to create the servo sequence, save the sequence, then use the Wave menu option to save the sequence as a WAV file.
This website will not let me upload the WAV files, the following links will pull the WAV files off a separate server. Click the link below to download the WAV file.
