Mini Self-Opening Box w/Arduino Nano, Switch & 4 x AA Battery

The video tutorial covers the process of troubleshooting and modifying an Arduino box. Initially, the presenter identifies a problem with the LCD screen, which is traced back to a faulty Arduino board. The presenter then decides to make modifications, including rewiring the box to run on AA batteries and adding a flip switch for convenience. The Arduino Uno board is replaced with a more compact Arduino Nano board. Component changes, such as using a Metal Gear micro servo, are also discussed. The video concludes with testing the setup and plans for future improvements.
