I am designing a 3d printed ray gun prop from Call of Duty Zombies mode. I want to use neopixels for glowing and a speaker for sound effects. I’ve been having trouble finding a system that can do both without a lot of boards. All of the sounds add up to about 9.5 seconds of audio and I want to use 4 different light patterns for things like shooting and out of ammo.
I would love to read anyone’s experience with similar projects. Using a WAV shield is not really an option because there is no room to fit an Uno.
- Control neopixels.
- Store and play sound effects.
- Run on one cell LiPo battery.
- Be able to charge the prop easily.(accessible USB port
- Storing and playing sounds.
- Finding a board that will also control neopixels.
- Running the whole thing on one LiPo cell.
- I think that the Adafruit Feather M0 Adalogger may be able to do the job because it has 256k of programming memory on the chip allowing the possibility to store the audio in the program as in this method. If that doesn’t work, I think I should be able to use the A0 analog output pin (since it has a DAC) to drive a speaker with an amplifier. I really want to avoid using a bunch of different components since space is a bit limited.
- Essentially this guide using the below components plus an extra button or two.
Adafruit Audio FX Mini + Audio Amplifier + Adafruit Trinket 3.3V(for LEDs only) + Adafruit Lipo Charger Backpack
Does anyone know if using the Feather Adalogger with an amplifier will be able succeed? Does the M0 architecture significantly change the methods for Arduino programming?
All help is greatly appreciated!
