Lego Monorail Garage test 4

This garage employs the mechanism already considered. The shutter doesn’t use any special shutter parts. The shutter opens and closes, and the rail expands and contracts. One motor drives both. The time required for opening and closing was measured to determine the rotation time of the motor. A program is created with “LEGO® POWERED UP“ to control the rotation time of the motor. Note: This mechanism, please see “Lego Monorail Garage test 3“.
