@copilot Necesito hacer un circuito de 12v que cuando lo active mandé un pulso negativo y cuando lo desactive me mande otro pulso negativo

Para crear un circuito que envíe un pulso negativo tanto al activarse como al desactivarse, podrías usar un circuito con temporizadores como el 555 en configuración monoestable (también conocido como un "estirador de pulso") o algún otro circuito integrado que tenga esta funcionalidad.
Aquí tienes un enfoque general utilizando un temporizador 555 en configuración monoestable:
  1. Componentes Necesarios:
    • 555 (1 unidad)
    • Resistencias y capacitores para configurar el tiempo del pulso
    • Un interruptor para activar y desactivar el circuito
    • Transistores para invertir la polaridad del pulso, si es necesario
    • Fuente de alimentación de 12V
  2. Funcionamiento:
    • Coloca el 555 en configuración monoestable para generar un pulso de salida en su activación.
    • Cuando el interruptor se cierra, el 555 es activado por un frente de bajada (pulso negativo), generando un pulso de salida.
    • Para el desactivado, se podría integrar un circuito similar pero invertido o usar una lógica que detecte la apertura del interruptor y genere otro pulso.
  3. Conexiones Básicas:
    • El pin 2 del 555 se conecta al interruptor para detectar la caída de voltaje.
    • Configurar los pines 6 y 7 con una resistencia y un capacitor adecuados para determinar la duración del pulso.
    • El pulso negativo que deseas de salida puede ser conseguido invirtiendo el pulso positivo original mediante un transistor configurado como inversor.
Si quieres, podemos detallar más este circuito o ajustar alguna parte específica. ¿Cómo te gustaría proceder?
