I combined two adafruit tutorials to create this:

https://learn.adafruit.com/gravity-falls-memory-gun?view=all

https://learn.adafruit.com/lightsaber-rp2040?view=all

Here are the parts I bought from adafruit:

  • Laser Diode - 5mW 650nm Red
  • Thin Plastic Speaker w/Wires - 8 ohm 0.25W
  • Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier
  • Lithium Ion Cylindrical Battery - 3.7v 2200mAh

I already had buttons and wires and solder and I've attached my code with the changes I made. I left some of the light saber code included but commented out in case you want to add some more effects.
