How to Play: Each knob has eight default settings. Turning each knob to a specific position triggers the lock and lights. The sound effect version also produces a sound effect when the mechanism is triggered.
Features:
1. Can trigger the lock and light.
2. The controller can directly power the 12V electromagnetic lock and light.
3. After the mechanism is triggered, it can be reset by powering it back on or by missetting the position.
4. Audio editing is supported. Audio is stored on a TF card in MP3 format. Two audio tracks are included: the first is the power-on audio, and the second is the triggering audio. A silent file can be used to replace the audio you don't want to play.
