1) Learning the Hardware
In order to play custom sounds, you need to have a Micro SD Card. It comes with a MicroSD and adapter.
If getting sound files from the computer you need to put the MicroSD inside the SD adapter so it will fit into your computer or standard card reader. It is important that the prongs are both pointing in the same direction as shown.
To Place into your computer place the MicroSD completely inside the SD adapter correctly and place the assembly into the computer as shown.
After you add the files, then remove the MicroSD card from the SD adapter and place into robot. IMPORTANT: Insert card all the way in with your nail, until your hear card “click”. Also, reboot robot by TURNING OFF AND ON ROBOT
2) How to Play a Sound from the Memory Card
Add in the code “call sound.play(#)” Where instead of #, put the number of the sound file that you are wanting to play.
Important: Only put the actual number and not the p#.
