Fuente de AlimentaciónFuente de 5 V y GroundLa fuente de 5 V alimenta todos los bloques. El terminal de tierra se conecta al Ground.
Entrada de TensiónPotenciómetroEl potenciómetro proporciona la tensión variable (0 a 5 V) que se conecta a la entrada no inversora de cada comparador.
Generación de UmbralesRed de divisores (utilizando Resistor)Se implementa una red divisor para obtener los niveles de referencia 1 V, 2 V, 3 V, 4 V y 5 V. Cada nodo de la red se conecta a la entrada inversora (-) del comparador asignado para ese umbral.
Comparadores- LM339 Comparator para umbrales 1 V a 4 V - Otro LM339 Comparator o LM393 Comparator para el umbral 5 V.Cada comparador se configura de la siguiente manera: - La entrada no inversora (+) recibe la señal del potenciómetro.- La entrada inversora (-) conecta al nodo de referencia del divisor (1 V, 2 V, 3 V, 4 V o 5 V según corresponda).- La salida (open collector) se prepara para activar la correspondiente indicación LED.
Indicadores Visuales (LEDs)5 LEDCada salida de comparador se conecta a un LED a través de una Resistor limitadora de corriente. Se conectan de forma que, al activarse el comparador, se encienda su LED asociado.
Conexiones de Pull-Up(Opcional, según el comparador seleccionado) Uso de ResistorSi el comparador es de tipo open-collector, agregar resistores pull-up en las salidas (o utilizar la resistencia integrada en la red de los LED) para asegurar niveles lógicos correctos.
Resumen de Conexiones Clave:
  1. Alimentación y Tierra:
    • El 5 V va a:
      • Los potenciómetros,
      • Los divisores de tensión para los umbrales, y
      • La alimentación de los comparadores y LED.
    • Todos los componentes conectan su pin de tierra al Ground.
  2. Entrada y Umbrales:
    • La señal variable del potenciómetro se reparte a los 5 comparadores (entrada positiva).
    • Cada comparador tiene su entrada inversora conectada a su nodo de referencia (1 V, 2 V, 3 V, 4 V o 5 V) obtenido mediante divisores resistivos.
  3. Salida e Indicadores:
    • La salida de cada comparador se conecta a su respectivo LED, en serie con un resistor de limitación.
    • Se recomienda verificar la polaridad de cada LED y, si es necesario, agregar resistores pull-up a las salidas de los comparadores open-collector.
Esta propuesta integra la fuente única de 5 V, el ajuste de tensión mediante el potenciómetro, la generación de umbrales con la red divisor y los comparadores que activan los 5 LED de indicación cuando la tensión supera los umbrales de 1 V a 5 V.
