arduino-ignore-button

This code is for an art project. The button will start the device, but ignore any extra button presses for a set amount of time.

Documentation of Arduino and LED button

The button I am going to use has a built-in LED, so I incorporated it into the design. The button has 4 terminals:

2 vertical: those are for powering the LED
2 horizontal: those are for the button

The relay has 2 positive and 1 negative for providing the power for triggering the Relay.

pins labeled S and + must be connected together to positive.
pin labeled - must be connected to negative (neutral)
Common - goes to one garage door switch terminal
NO (normally open) - goes to the other garage door switch terminal

Arduino

To button LED:

GND (ground) - goes to LED button
Digital ~10 - goes to LED button (neutral)

To button:

Digital ~9 - goes to button switch
GND (ground) - goes to button switch

To relay:

5V - goes to +/S on rely
Digital ~5 - goes to - on relay

Sound

I added sound February of 2023 using an Adafruit Sound Board.

To board:

5V - goes to Vin pin on sound board
GND - goes to GND pin on sound board
Digital 3 - goes to zero (0) pin on sound board
