Cart Lock

Shopping Cart lock/unlock app by RocketGod (@rocketgod-git).

Warning

This app plays audio at maximum volume automatically.

Requirements

Two WAV files must be placed in the WAV/ folder on the SD card:

Filename	Function
shopping_cart_lock.wav	Played when pressing Lock
shopping_cart_unlock.wav	Played when pressing Unlock

If either file is missing, the Lock and Unlock buttons will not appear.

Usage

Button	Action
Lock	Plays the lock WAV file on loop
Unlock	Plays the unlock WAV file on loop
Stop	Stops playback

The audio loops continuously until Stop is pressed or the app is closed.

The log panel at the top shows diagnostic output: file scan results, playback state, and any errors.

Notes

• Original .cu8 signal files by @jimilinuxguy
• Audio is output through the headphone jack or internal speaker at maximum volume
• The app requires WAV files to be present — it does not generate tones internally
