Gameplay:
Knocking on the door to a set rhythm triggers a mechanism (unlocking, lighting, or controlling a lever). You can modify the rhythm code and sound effects. The controller can directly power the 12V electromagnetic lock.
Key Features:
1. Modify the rhythm code. Press the "Set" button on the controller to start the rhythmic knocking. The controller will beep each time a rhythm is successfully entered. After all rhythms are entered, press the "Set" button again to confirm the rhythm code.
2. Modify the music content. The music can be stored in MP3 format and on a TF card. There are 16 audio tracks in total (the first track is the power-on music, the second track is the door opening music, the third track is not currently used, the fourth track is the rhythm setting prompt, the fifth track is the completion prompt, the sixth to fifteenth tracks are the 1st to 10th knock prompts when setting the password, and the sixteenth track is the 10th knock prompt). If you don't want to play a particular track, you can add a silent file instead. The controller includes a built-in speaker and supports external speakers.
3. Reset: After successfully triggering the mechanism, it will reset by powering it back on or automatically resetting after one minute.
