Gotta say, lovely project! I just finished wiring up everything only to find I ordered the wrong type of 3.7 500mA battery from amazon instead of adafruit. Just waiting for the right one to come into stock again.
I just plugged my Ray gun into my computer just to see if I can get the Raygun to play sounds and light up without the battery and when I turn it on all it seems to do is the battery is churping when the trigger is squeezed or its just idling. The green light is on perfectly fine but the neopixels do not light. Its just the frequency of the speaker churping changes when the barrel is open/closed and if the trigger is pulled.
Why in the world would this happen and how can I fix it?
