Lots of solutions? Cool! Like what?
Buzzer is some old piece of junk I found. 8ohm and says 25 watt and tied to a board that’s says DL-13.
LEDs are Chanzon, the 100 pack available online I bough off amazon for $6.
Board is an aduino 101.
I’m looking for the brightest and loudest I can get off the 3 volts I get on the output without spending tons of money
