Is an Arduino tutorial based on Beginner Kit Tutorial from DFRobot, you can buy Kit & access tutorials online here https://www.dfrobot.com/product-345.html.

Read description & circuit on each projects, and also practical directly by uploading code (.hex) to Arduino board over USB/Bluetooh to see what happen. For the project need debugging, you can use Serial Monitor features.

Here tutorials how to make Arduino can uploaded sketch from Android to Arduino Hardware over bluetooth:
