PAD Sound and Light Board
When I first started making Death Trooper helmets I began looking for a simple solution to adding sound and lights to the helmet. I also wanted to add sound and lights to my E-11D blaster. There were a number of solutions out there, but they all involved a lot of wiring and soldering. So I decided I wanted to make an easy to use little board that would combine together a small Arduino board with SD card reader and MP3 player. The result is our PAD Sound and Light Board. Truth is there isn't anything truly revolutionary about it, its just simple and easy to use in a pretty small package. Its also ver versitle so it can be used in any number of situations where you want to sink a sound file with an LED light.
The board is available in our store for $35. Add lights, a speaker, a few switches, and 5V power supply, and your ready to rock and roll. For more advanced users, a bit of programming knowledge helps.
Note that if you use use bare LEDs, then you will need to add in resistors onto the board. There are spots for them. If you use LEDs that are prewired with resistors already, then you need to add a wire jumper accross this section.
PowerThe board requires a 5V power supply such as that from a USB port. My favorite power source is these littel cyclinder rechargable USB power packs. (Do not use more than 5V or you can blow out the sound board.)
Another great solution is a little power board that will accept both 9-12V and convert it down to 5V. I use a 12V system in my DT armor so I added in one of these little boards. The can be found on Amazon here.
The Arduino board comes pre-programmed with simple code that can be used for a blaster or for cycling through sounds in a helmet. But if your a bit more advanced here is the code so you can modify it to do a lot more. I'm posting this code under the Creative Commons license. All I ask is that if you modify it to do something else cool, you will share it with me so I can post it here as well for others. You will also need the sound board libraries which can be found here.(https://github.com/DFRobot/DFRobotDFPlayerMini/archive/1.0.3.zip)
Below is the code I used. You are free to modify it to fit your needs.
