Halloween Raspberry Pi

A basic Node.js project to trigger sound effects via a Raspberry Pi. A quick project which allows the attachment of a button to the GPIO ports of the Pi and triggers random sound effects.

Installation

Clone the project and install the node modules with:

npm install

You will need to ensure that the alsa.h header can be found in order to build the node-speaker module. Do this with the following:

sudo apt-get install libasound2-dev

Once installed you can run the project with:

npm start

Usage

The breadboard should be setup in a similar way as the onoff module. The button is attached to Gpio 4 and I've added 4 LEDs attached to GPIOs 14, 15, 18 and 23 for my project. These can be altered in config/config.js to your own needs and you will need to rewire your breadboard accordingly. Have a look at this very helpful Raspberry Pi GPIO pinout from Gadgetoid for more details.

The code will trigger all LEDs in the leds array in config/config.js to light when the sound effect is played. Alter the soundFiles array in config/config.js to add new sound effects to trigger. These are currently triggered randomly when the button is pressed.

Run the project with npm start.
