LED Control with D Flip-Flop

flux

A continuación se propone una configuración sencilla para lograr que el LED cambie de estado con cada pulsación del botón mediante un flip-flop tipo D:
  1. Flip-Flop D:
    • Usa un 74HC74 que incluye dos flip-flops D.
    • Para el flip-flop que usarás, conecta su salida inversa (Q') a la entrada D para lograr la función de toggle en cada flanco de reloj.
  2. Botón Pulsador:
    • Agrega un Push_Button que actuará como señal de reloj (clock) para el flip-flop.
    • Asegúrate de que el botón tenga los componentes de pull-up o pull-down apropiados (según el diseño del flip-flop) para generar un pulso limpio al presionar.
  3. LED con Resistencia:
    • Añade un LED y conecta una resistencia limitadora (por ejemplo, R1 con un valor de 330Ω o 1kΩ) en serie para proteger el LED.
    • La salida Q del flip-flop será la que controle el encendido y apagado del LED.
  4. Alimentación y Rutas de Referencia:
    • Conecta los pines de alimentación del 74HC74 a VCC y GND.
    • Asegura que las señales asíncronas (Clear y Preset) estén en niveles lógicos adecuados (por lo general, conectados a VCC para evitar resets inesperados).
    • Añade un componente Ground para todas las conexiones de tierra.
Esta configuración permite que cada vez que presiones el botón, el flanco de reloj active el flip-flop y se invierta la salida, cambiando el estado del LED.
