- First Touch: Activates the breathing light effect, where the lights gently fade in and out.
- Second Touch: Switches to a constant light effect, keeping the LEDs steadily illuminated.

6. Maintenance
Proper maintenance will ensure the longevity and smooth operation of your ROBOTIME LGX02 Marble Run.

- Lubrication: If any gears or moving parts become stiff, apply a small amount of wax (often included in the kit) or a dry lubricant to the contact points. Avoid oil-based lubricants, which can attract dust.
- Storage: Store the marble run in a dry environment, away from direct sunlight and extreme temperature changes, which can cause the wood to warp or crack.
