The bridge and the two wings of the gate of the Monastery of Incense can be moved by 3 servo motors.
The bridge has 4 LEDs, which switch on and off in pairs.
There are 2 Touch Sensors built into the Incense Monastery . One of them starts your program, the bridge opens, the LED pairs light up one after the other and the two wings of the gate open.
On the second, the structure is restored to its initial state.
The operation of the Incense Monastery is identical to that shown in P3, but it is triggered by an IR Photoreflector.
At the press of 1 button, the Incense Monastery resets to its default position, the gate wings close, the LED pairs switch off and the bridge closes.
The princess in front of the infrared sensor also has an infrared sensor mounted on, which activates her program when she is placed in front of the castle’s sensor.
