1. Button State Reading:
   • Reads the state of two buttons connected to digital pins boton1Pin and boton2Pin.
2. Debounce Logic:
   • Implements a debounce mechanism to ensure button presses are valid, essentially filtering out noise from the physical bouncing of the button contacts.
3. LED Control:
   • Button 1 Logic:
     • When the button connected to boton1Pin is pressed and the system is not already "on" (sistemaEncendido is false):
       • Waits 50 milliseconds for debounce delay.
       • Confirms the button state is still pressed.
       • Turns led1Pin on and led2Pin off.
       • Sets sistemaEncendido to true.
   • Button 2 Logic:
     • When the button connected to boton2Pin is pressed and the system is "on":
       • Waits 50 milliseconds for debounce delay.
       • Confirms the button state is still pressed.
       • Turns led1Pin off and led2Pin on.
       • Calls apagarServos() to presumably turn off or reset something connected to servos (although the function itself is not shown).
       • Sets sistemaEncendido to false.
4. Comments:
   • Placeholder comment indicating where additional logic can be added.

• Button and LED Pins: boton1Pin, boton2Pin, led1Pin, led2Pin.
• Global Variables for Button States and System State: botonPin1State, botonPin2State, sistemaEncendido.

1. Debounce: Estás implementando un debounce básico con un simple delay(50). Esto funciona, pero puede causar que el microcontrolador quede inactivo durante esos milisegundos y podría ser menos eficiente si hay otras tareas que ejecutar. Una alternativa podría ser implementar una lógica de debounce que no use delay, como un contador o un temporizador.
2. Comentarios: Asegúrate de que los comentarios del código expliquen claramente las partes más complejas o específicas. Aunque este fragmento es relativamente sencillo, un comentario detallado sobre el propósito de apagarServos() sería útil.
3. Funciones como apagarServos(): Esta función se menciona pero no se ve en el código proporcionado. Asegúrate de que esté bien definida en tu código completo. Esto podría significar incluir acciones específicas para apagar los servos, posiblemente relacionados con los controladores de motores, como el TB6612FNG en tu proyecto.
4. Variables y Configuración: Asegúrate de que las variables como boton1Pin, boton2Pin, led1Pin, led2Pin, y sistemaEncendido estén correctamente definidas en la configuración inicial del programa (setup()), incluyendo la configuración de pines como entradas o salidas usando pinMode().

• Servo Objects: Four servos are defined using the Servo library.
• Pin Assignments: Pins are assigned for servos, buttons, and LEDs.
• Ultrasonic Sensor Pins: trigPin and echoPin are used for measuring distance.
• Status Variables: Variables to track button states and the system's operational status.

• Attach Servos: Attaches each servo to its respective pin.
• Configuring Pins:
  • Buttons are set as inputs with internal pull-up resistors.
  • LEDs are set as outputs.
  • Ultrasonic sensor pins configured appropriately.
• Initial LED State: Both LEDs are turned off initially.

• Button Handling:
  • Debounce logic for button presses is managed by checking if they are low.
  • Toggles system state based on button input.
• Distance Measurement:
  • Uses ultrasonic sensor to measure distance by sending a pulse and recording the duration of the echo.
  • Converts the echo duration into a distance in centimeters.
• Servo Control:
  • Actuates servos based on the measured distance:
    • Different target positions for servos are set depending on proximity thresholds $10 , \text{cm}$, $20 , \text{cm}$, $30 , \text{cm}$, $40 , \text{cm}$.
  • If the distance exceeds $40 , \text{cm}$, all servos are set back to a neutral position.

• Resets all servos to a neutral position $90^\circ$, which is commonly used to stop servos or set them to a default state.

• Debounce Timing: You might consider adding software debounce more explicitly, with a non-blocking approach.
• Neutral Servo Position: Ensure that the position set in apagarServos is appropriate for your application. You might need to adjust the "neutral" position depending on the mechanical setup.
• Code Organization: It's well organized, but adding comments or segmenting functionality into more modular functions could enhance readability and maintainability.

1. Libraries and Initialization:
   • Includes the Servo library to control servo motors.
   • Defines servo objects and assigns them to pins.
2. Pin Assignments:
   • Defines pins for servos, buttons, LEDs, and an ultrasonic sensor.
   • Configures pins using pinMode in the setup function:
     • Buttons are configured as INPUT_PULLUP, which means they are active low (they read LOW when pressed).
     • LEDs and the ultrasonic sensor's trigPin are configured as OUTPUT.
     • The ultrasonic sensor's echoPin is configured as INPUT.
3. Main Loop Logic:
   • Button Press Handling:
     • Checks button states with digitalRead. For debounce, it assumes proper mechanical button design with no additional code for bounce.
     • Turns on/off LEDs and changes system state based on button presses.
   • Ultrasonic Sensor Reading:
     • Uses pulseIn to measure echo time and calculate distance.
   • Servo Control:
     • Depending on the measured distance, moves servos to specific positions.
     • If the distance is greater than 40 cm, it calls apagarServos().
4. Debounce:
   • The code uses input pull-up resistors for buttons, this simplifies the wiring and ensures a stable state. However, there is no debounce logic except relying on delay() calls. Consider improving this with non-blocking methods if necessary.
5. Function apagarServos:
   • Sets all servos to a neutral position (90 degrees), which effectively "turns off" their motion.

• Debounce Logic: Consider implementing a non-blocking debounce method to improve button reliability, especially if further functionality might be added.
• Distance Thresholds: Ensure the distance thresholds and servo positions fit the application's physical setup.
• Comments: While there are some comments, additional comments could further clarify specific logic, especially around sensor handling and servo positioning.
• Component Feedback: Based on the physical setup, observe the actual behavior of servos and ensure their response to distance changes is as expected.

1. Libraries and Servo Initialization:
   • Uses the Servo library for controlling the servos.
   • Initializes four servo objects.
2. Pin Definitions:
   • Assigns pins for servos, LEDs, buttons, and an ultrasonic sensor.
   • Utilizes internal pull-up resistors for button inputs.
3. Setup Function:
   • Attaches servos to their respective pins.
   • Configures buttons, LEDs, and ultrasonic sensor pins with pinMode().
   • Ensures LEDs are off at startup.
4. Loop Functionality:
   • Button Handling:
     • Reads the state of buttons. If pressed (LOW due to pull-up configuration), it toggles the system state.
   • LED Indicators:
     • Turns on/off LEDs to indicate system state.
   • Distance Measurement:
     • Sends a pulse and measures the echo return time to calculate distance.
   • Servo Control:
     • Actuates servos based on the measured distance with specific thresholds.
   • ApagarServos Function:
     • Resets all servos to a neutral position (90°) for a safe stop.

• Debouncing: While buttons are checked for state changes, you could implement a software debouncing mechanism to ensure more reliable button presses.
• Timing: Make sure the 10 µs trigger pulse is consistent with your sensor's requirements. In most cases, it's fine, but it's always good to refer to the sensor's datasheet.
• Maximum Range for Servos: Ensure servo limits (0-180°) align with their actual range to prevent mechanical issues.
• Distance Calculation: The speed of sound is considered with $0.034 \text{ cm/µs}$. If the environment temperature varies significantly, a correction factor might be applied for precise measurements.
• Additional Functions: If the application expands, consider modularizing the code further by splitting into more functions for readability and maintenance.

1. Setup Phase:
   • Servo Initialization: Four servo motors are attached to specific pins and initialized.
   • Pin Configuration:
     • Buttons are set up with internal pull-up resistors, making them active low.
     • LEDs are configured as outputs for status indication.
     • Ultrasonic sensor pins are appropriately configured.
   • Initial LED State: Both LEDs are turned off, indicating the system starts in an off state.
2. Loop Phase:
   • Button Handling:
     • Checks the button states and changes the system's state based on which button is pressed.
   • Ultrasonic Distance Measurement:
     • Sends a pulse to the ultrasonic sensor and measures the echo time to determine the distance.
     • The distance is calculated and used to control the servo motors.
   • Servo Control:
     • Moves servos based on the measured distance thresholds.
3. Stop Servos Function:
   • Resets all servos to a neutral position when turning off.

• Debounce the Buttons:
  • Implement a debounce algorithm to prevent false triggers due to button bounce. This can be done with software debounce without blocking delays or adjusting hardware.
• Code Maintenance:
  • Comments are appropriate; ensure they match the code logic. Consider adding comments for future reference, especially around the servo movements and distance control logic.
• Efficiency:
  • Ensure that delayMicroseconds provides sufficient time for sensor stabilization. The current setup seems sufficient, but testing might prove whether adjustments are needed.
• Functionality Verification:
  • Check that the neutral position (90 degrees) aligns with the mechanical setup and that it effectively "stops" or resets the servos to a desired position.
• Edge Cases:
  • Consider cases where sensor readings might be out of expected range or when no object is detected (e.g., handling duracion returning 0).

• Debouncing: Implemented a software debounce mechanism using the millis() function to ensure that button presses are accounted for only once over a specified debounce period.
• State Management: Used separate variables to track the last and current state of each button, which helps in identifying state changes as well as managing debouncing effectively.
• Commentary: Comments are adjusted for clarity and understanding of the logic and flow.
