Paso 10: Prueba el relé de
Se necesita:- Cable USB
Podemos agregar en un paso intermedio para asegurarse de que el escudo de relé está trabajando.
- Desconecte la conexión de altavoces a la pantalla (esto es solo temporal por lo que podemos escuchar el relé del interruptor)
- Subir el código a tu Arduino
- Presione el botón en su protoboard.
- Debería escuchar el relé haga clic encendido y apagado (se muestra en el video). Puede que necesite mover las clavijas de conexión el escudo de relé a Arduino un poco hasta que ambos relés son clic y alternativamente.
- Una vez que sabemos esto es que podemos conectar los altavoces de nuevo en.
