A continuación se muestra una sugerencia para colocar los componentes del circuito y conectarlos. Se incluyen todos los elementos necesarios para que, al detectar luz, se encienda un foco y, cuando no se detecte, se active un buzzer.
Componentes a agregar:

Conexiones sugeridas:
  1. Divisor de voltaje con LDR:
    • Conecta un extremo de LDR1 a VCC (5V).
    • Conecta el otro extremo de [LDR1] a un nodo común (llamémoslo Nodo_LDR).
    • Conecta R1 entre Nodo_LDR y GND.
    • El Nodo_LDR se usará como señal variable según la luz ambiental.
  2. Divisor de referencia:
    • Conecta R2 desde VCC a un nodo de referencia (Nodo_REF).
    • Conecta R3 desde Nodo_REF a GND.
    • Nodo_REF será el voltaje de comparación para los comparadores.
  3. Configuración del LM393 (U1):
    • Comparador A (U1A):
      • Conecta el pin no inversor (+) a Nodo_LDR.
      • Conecta el pin inversor (–) a Nodo_REF.
      • La salida de U1A se utilizará para la condición de luz presente.
    • Comparador B (U1B):
      • Conecta el pin no inversor (+) a Nodo_REF.
      • Conecta el pin inversor (–) a Nodo_LDR.
      • La salida de U1B se utilizará para la condición de baja o nula luz.
      • (Nota: Debido a que las salidas del LM393 son colector abierto, asegúrate de que tengan un pull-up a VCC si es necesario).
  4. Control del Foco:
    • Conecta la salida de U1A a través de R4 a la base de Q1 (transistor NPN).
    • Conecta el emisor de [Q1] a GND.
    • Conecta el colector de [Q1] al terminal negativo del Foco.
    • Conecta el terminal positivo del [Foco] a VCC.
      • Se puede incluir un resistor en serie al foco si es necesario para limitar la corriente.
  5. Control del Buzzer:
    • Conecta la salida de U1B a través de R5 a la base de Q2.
    • Conecta el emisor de [Q2] a GND.
    • Conecta el colector de [Q2] al terminal negativo del Active Buzzer.
    • Conecta el terminal positivo del [Active Buzzer] a VCC.
  6. Alimentación:
    • Asegúrate de que VCC (5V) esté disponible para alimentar los divisores, el LM393 y las cargas.
    • Todas las conexiones a tierra deben unirse a GND.
Esta configuración asegura que:
  • Cuando hay luz:
    La tensión en Nodo_LDR sube, haciendo que en U1A la señal (no inversora) supere la referencia. Así, la salida de U1A activa [Q1] mediante [R4], permitiendo que el [Foco] se encienda.
  • Cuando no hay luz:
    La tensión en Nodo_LDR baja, invirtiendo la comparación en U1B. La salida de U1B activa [Q2] vía [R5], permitiendo que el [Active Buzzer] se active.
