@copilot dime como hacer un circuito con dos leds usando un relay ese circuito debe verse el normalmente abierto y normalmente cerrado

copilot

Para diseñar un circuito que utilice dos LEDs y un relé, donde uno de los LEDs esté conectado a través del contacto normalmente cerrado (NC) del relé y el otro a través del contacto normalmente abierto (NO), puedes seguir los siguientes pasos. Asumiré que estás usando un relé de 5V y LEDs que operan a aproximadamente 20 mA, y que el circuito será alimentado por una fuente de 5V. Los componentes adicionales incluirán resistencias para limitar la corriente a través de los LEDs.

Lista de componentes

Relé 5V (con contactos NO y NC)
2 LEDs (asumiendo LEDs rojos con una caída de tensión de aproximadamente 2V)
2 Resistencias para limitar la corriente de los LEDs (calcularé el valor basándome en una corriente de 20 mA)
Fuente de alimentación de 5V

Cálculo de las resistencias

Para calcular el valor de las resistencias de limitación de corriente para los LEDs, puedes usar la ley de Ohm. La fórmula es:

R = \frac{V_{fuente} - V_{LED}}{I_{LED}}

Donde:

$R$ es la resistencia necesaria.
$V_{fuente}$ es la tensión de tu fuente de alimentación (5V).
$V_{LED}$ es la caída de tensión a través del LED (2V).
$I_{LED}$ es la corriente deseada a través del LED (20mA o 0.02A).

Entonces, para un LED rojo:

R = \frac{5V - 2V}{0.02A} = 150\Omega

Asumiendo un valor de resistencia estandarizado, podrías usar una resistencia de 150 ohmios para cada LED.

Conexiones del circuito

Conexión de la fuente de alimentación: Conecta el $+5V$ de la fuente de alimentación al pin de la bobina del relé y al ánodo de cada LED a través de una resistencia de 150 ohmios respectivamente.
Conexión de tierra: Conecta el GND de la fuente de alimentación al otro pin de la bobina del relé, y también al GND de tu proyecto.
Conexiones del relé a los LEDs:
- Para el LED que estará normalmente encendido (a través del NC): Conectar una resistencia de 150 ohmios al contacto NC del relé. Conecta el otro extremo de esta resistencia al ánodo del primer LED. Conecta el cátodo de este LED al GND.
- Para el LED que se encenderá cuando el relé esté activado (a través del NO): Conectar una resistencia de 150 ohmios al contacto NO del relé. Conecta el otro extremo de esta resistencia al ánodo del segundo LED. Conecta el cátodo de este LED al GND.

Resumen de las conexiones

Conecta GND a Pin del Relé:Bobina(-), LED1:Cátodo y LED2:Cátodo.
Conecta +5V a Relé:Bobina(+), a través de una R1 de 150 ohmios a LED1:Ánodo, y a través de una R2 de 150 ohmios a LED2:Ánodo.
Conecta Relé:NC a R1:1 lado contrario al LED.
Conecta Relé:NO a R2:1 lado contrario al LED.

Este diseño básico activará uno de los LEDs cuando el relé esté inactivo (normalmente cerrado) y el otro cuando el relé se active (normalmente abierto). Ajusta los valores de la resistencia según sea necesario en función de las especificaciones exactas de tus componentes.
