Simple DIY Horn for RC Cars (NE555)

I've seen other videos showing horns and buzzers but they don't sound close enough to any actual horn to work. I also realized using a bike horn at over 100db would probably be a bad idea. A simple 555 circuit seems the smallest/easiest way to go about it without getting into more modulation to improve the sound of it. I think with the proper speaker enclosure or amplifier guide it can not only be louder but sound more horn-like. This circuit produces square waves around 320hz to 380hz. I also found 400-450hz or so at around 15% duty to sound pretty good. 6v paired with this small speaker seems to work pretty good but it might sound better at 12v using a more powerful speaker that can handle it better. Use this circuit combined with the Aux On/Off circuit like this ( https://www.amazon.com/Remote-Control... ) and set the desired channel to a momentary on function. The output voltage from the receiver will directly power the horn circuit.
