So, I would like to build a rats repellent circuit. I dont want to kill them, just keep them away. I did this all from ear and experimentation, as well as spending sheer amounts of time on it, so please don't over criticize. Hi folks, Ive got a bit problem with rats, they are destroying my garden. Feel free to use it for any of your projects or even build upon the code.
#Arduino piezo no sound code
I thought the world would be a better place if I put the code out there for public use (robot sentries or battle bots playing this before combat helps dramatic tension). Long leg of piezo: pin 4, short leg: GND.īyte buttonPin = 10 // pin for momentary switch (between Pin 10 and GND).Hey guys, here is just a code for playing the "Eye of the Tiger" intro by Survivor (on a piezo buzzer)that I made.
Who fans! byte piezoPin = 4 // pin for piezo. I was monkeying around today, and I got a reasonable sonic screwdriver sound out of a piezo, without sampling a. But nobody write sheet music for sound effects, you know what I mean? If I could just get something like "oh yeah, the sonic screwdriver sound is BBBGAADEEFFGAGAGAAABBE" I would be golden. I mean, if I wanted to play mary had a little lamb on my buzzer, I could just look up the hertz values for the notes (which are in the melody library already) and plug them in. I made some good progress on the concept today, but everything sounded like 8bit video game music, which isn't really the effect I'm going for. I want, max, like a series of 20 tones I can loop that make a nifty sci-fi sound.
#Arduino piezo no sound full
I've downloaded a program that will convert any audio file to hertz values, but even with the shortest sound effects I always end up with a page or two full of numbers, which is too many. So no nifty pots in combination for me!īasically I just want to take some sci-fi sound effects and convert them to hertz so I can use them with tone(frequency,duration). That looks like a really fun music toy to play with, but I'm running a tiny piezo buzzer in a tiny space, and I just need to hit a switch and have it play a little sound effect. It probably just needs small adjustments from someone with a more trained ear: tone(buzzerPin,2200) // then buzz by going highĭelayMicroseconds(10000) // and waiting moreĪhhhhhh! Why did my subscription to this thread not notify me that a cool person had replied to it!?!?!
#Arduino piezo no sound software
I'm mostly a software person, so I prefer to do it with code rather than more components)Īnyway, here it is. It will produce sound when IO pin is low and it will be quiet when IO pin is high. (I don't want to build an oscillator either. As mentioned above, this buzzer board is 'active low'. It's close, but it's pretty irritating and I'd like to smooth it out and get it doing that nice oscillating thing. Here's the sorta-kinda-wibbly-wobbly code I've got running the buzzer right now. Here's what a sonic screwdriver sounds like, for reference:
It shouldn't really be that difficult, I just have a terrible ear and couldn't deconstruct a sound if my life depended on it. I don't want to use a speaker, just a buzzer. I've got the Melody function working with a piezo buzzer, but I'm actually trying to generate creepy sci-fi type sounds like a sonic screwdriver or a ray gun or that theremin sound from twilight zone and such.
