En este proyecto se fabricará una rocola utilizando arduino

Supplies

Arduino (UNO or Mega)

Buzzer pasivo

Jumpers

Protoboard

Resistencia 220 ohm

LCD 16X2

Push button

Switch

MDF o una pequeña caja para la estructura

Opcional

Acceso a cortadora laser

Step 1: Fabricación De Caja De Soporte

Si se cuenta con acceso a cortadora laser, se debe diseñar una caja utilizando la pagina web https://es.makercase.com de 6x6x3 pulgadas. Si no se cuenta con la herramienta de corte laser

se puede utilizar un recipiente plástico.

Step 2: Realizar El Cableado De LCD

Realizar el cableado de la pantalla LCD con el Arduino MEGA como se indica en el diagrama utilizando los jumpers.

Nota: El potenciometro puede ser sustituido por una resistencia de 220 ohm.

Step 3: Cableado De Buzzer

Realizar el cableado del Buzzer como se indica en el diagrama. Cabe mencionar que la entrada del buzzer se puede conectar a cualquier otra entrada siempre que la misma sea PWM.

Step 4: Cargar Código a Arduino

A continuación cargue el siguiente código a la plataforma Arduino
