copilot Entiendo que deseas diseñar un oscilador utilizando el chip 555. Aquí están algunos pasos que puedes seguir para hacer esto. Conecta el pin 1 (GND) del IC 555 a la terminal negativa de tu fuente de alimentación (0V). Conecta el pin 8 (VCC) del IC 555 a la terminal positiva de tu fuente de alimentación (11V). Conecta la resistencia de 10kΩ (R1) entre el pin 8 (VCC) y el pin 7 (DISCHARGE) del 555. Conecta tu potenciómetro de 100kΩ (R2) entre el pin 7 (DISCHARGE) y el pin 6 (THRESHOLD) del 555. Junta los pines 2 (TRIGGER) y 6 (THRESHOLD) juntos y conecta los pines unidos al lado negativo de tu condensador de 10nF (C). Conecta el lado positivo del condensador de 10nF (C) a VCC (el pin 8). Conecta el pin 4 (RESET) al VCC si no quieres usar la función de reset. De lo contrario, puedes conectar una señal de reset aquí. Conecta el pin 3 (OUTPUT) del 555 al terminal positivo de tu resistencia de 470Ω. Conecta el otro terminal de la resistencia a tierra. El condensador de 10uF debe estar conectado en paralelo a la alimentación (entre VCC y GND) para suavizar cualquier ruido en la fuente de alimentación de 11V. Te sugiero que experimentes con el valor del potenciómetro (R2) hasta que consigas el Duty Cycle deseado. Por lo general, es posible cambiar la frecuencia del pulso y ajustar el Duty Cycle utilizando este control. Si, después de realizar estas conexiones y ajustes, aún no puedes obtener el Duty Cycle deseado, podría ser indicativo de que los valores de resistencia y condensador que tienes no son adecuados para tu rango de frecuencia y Duty Cycle objetivo. Para que obtengamos un Duty Cycle del 75%, necesitamos usar el chip 555 en modo astable y debemos calcular los valores de R1 y R2 (resistencia total de carga y descarga respectivamente) que nos ayude a conseguir esto. El tiempo de alta (T_high) y el tiempo de baja del ciclo (T_low) de la oscilación salen determinados por R1, R2, y C (el condensador). Se pueden usar las siguientes fórmulas para calcularlos: T_high = 0.693 * (R1 + R2) * C T_low = 0.693 * R2 * C Duty cycle = ( T_high ) / ( T_high + T_low ) Para un Duty Cycle de 0.75: Estableceremos R1 como la resistencia de 10 kilohmios que se proporcionó. Con el potenciómetro de 100 kilohmios como R2, podemos variarlo para ajustar el Duty Cycle según necesitemos hasta que se llegue a la relación deseada. Considerando que el condensador C es el condensador de 10 nF que se proporcionó, anteriores declaraciones son bajo supuesto que el tiempo de operación (T = T_high + T_low) caiga en un rango aceptable. Para el esquemático: Conecta VCC de tu 555 al terminal positivo de tu fuente de voltaje de 11V y GND a tierra. Conecta los pines 2 (TRIGGER) y 6 (THRESHOLD) juntos y al lado negativo de tu condensador de 10nF. Conecta el lado positivo del condensador a VCC. Conecta el pin 3 (OUTPUT) al terminal positivo de tu resistencia de 470 ohmios. Conecta el otro terminal de la resistencia a tierra. Conecta tu resistencia de 10 kilohmios entre VCC y los pines 2 y 6 del 555. Finalmente, conecta tu potenciómetro entre los pines 2 y 6 y el pin 7 (DISCHARGE) del 555. El condensador de 10uF debería estar conectado en paralelo a la alimentación para suavizar cualquier ruido en la alimentación de 11V. Estas son mis suposiciones y pasos sugeridos pero recuerda variar el potenciómetro hasta conseguir el Duty Cycle deseado en caso de no conseguirlo de forma inmediata. Si por alguna razón no puedes conseguir el Duty Cycle de 75%, es posible que las resistencias y condensadores proporcionados no sean los adecuados para el rango de frecuencia y Duty Cycle deseados. En tal caso, puede que tengas que utilizar otros valores de componentes.

Project Overview: This project is an enhanced LED blinking circuit that goes beyond a simple 555 timer-based design. It incorporates additional features such as random blinking patterns, speed control, and a start/stop function. The project utilizes a microcontroller, such as an Arduino or Raspberry Pi, to control the blinking patterns, speed, and start/stop functionality. LED Blinking: The board features a total of 8 LEDs that blink in various random patterns. When the board is powered on, even before user interaction, the LEDs start blinking randomly, creating an eye-catching display. Each LED has its own current-limiting resistor to ensure proper current flow and prevent damage. The microcontroller is programmed to generate random blinking patterns for the LEDs, ensuring that the LEDs do not blink in a predictable or sequential order. This random blinking adds an element of unpredictability and visual interest to the project. Speed Control: The board includes two speed control buttons that allow the user to adjust the blinking speed of the LEDs. Button 1 is designated as the "fast" button, increasing the blinking speed when pressed, while Button 2 is designated as the "slow" button, decreasing the blinking speed when pressed. The speed control provides a range of blinking speeds, from a slow, gradual blink to a rapid, strobe-like effect. The microcontroller monitors the state of the speed control buttons and adjusts the blinking speed accordingly. Start/Stop Functionality: A third button serves as a start/stop control. When pressed, it toggles the blinking of the LEDs on or off. This allows the user to freeze the blinking pattern at any desired moment or resume the blinking when desired. The microcontroller handles the start/stop functionality by turning the LEDs on or off based on the state of the start/stop button. Manual Speed Adjustment: In addition to the speed control buttons, the board includes a potentiometer or variable resistor. This component allows the user to manually adjust the blinking speed of the LEDs by turning the knob or sliding the control. The manual speed adjustment provides more precise and customizable control over the blinking speed compared to the preset speeds of the buttons. The microcontroller reads the analog value from the potentiometer and adjusts the blinking speed accordingly. Power and Connectivity: The board is powered through a USB-C or USB-micro B connector, allowing it to be easily connected to a power source such as a computer or wall adapter. A voltage regulator may be included to ensure a stable and appropriate voltage supply to the components. A power switch is incorporated to conveniently turn the board on or off.
