Day 3 progress

Today, we find solutions to lifting the roof: 1. to use an elevator model. 2. to use a servo motor

Charles figured out the servo motor code, and I made an elevator mechanics proof.

  // Wait for the serial port to connect  while (!Serial) {    ; // Wait for the serial port to connect. Needed for native USB port boards.  }
  // Set the LED pin as an output  pinMode(ledPin, OUTPUT);
  // Print a startup message  Serial.println("Pressure Sensor with LED Example Initialized");}
void loop() {  // Read the analog value from the sensor (0 to 1023)  int sensorValue = analogRead(fsrPin);
  // Print the sensor value to the serial monitor (optional)  Serial.print("FSR Value: ");  Serial.println(sensorValue);
  // Check if the sensor value exceeds the threshold  if (sensorValue > threshold) {    Serial.println("Pressure Sensed");  // Print when pressure is detected
    // Turn on the LED when pressure is sensed    digitalWrite(ledPin, HIGH);  } else {    // Turn off the LED when no pressure is sensed    digitalWrite(ledPin, LOW);  }
  // Add a small delay to make the serial output readable  delay(500);  // 500ms delay}

First try and found out the hole should be more near the edge so the pieces could open fully.
