imagine you have say four pins. each pin represents a bit of data (ie, we have a four bit byte).
By connecting a network of resistors to the outputs of the four bits, you basically get a voltage value that is a ratio of the byte value compared to a full byte as a voltage of the voltage that is logical 1.
So if we are dealing with four bits and the Arduino, 1111 will give us 5V and 0000 will give us 0V. There are sixteen possible voltage values (inclusive 5v and 0v), because there are 4 bits.
i have not heard of that particular IC, where can you get it from? i have many resistors just lying around, so.. cheap, easy and i don't have to go anywhere to get anything.
i do not have the exact code for these examples anymore. but i have made a slightly altered version that acts a little differently. i will put this new version up etc.
hey, if you look under my videos for a newer one called "Arduino Noise Maker", then under the video info you can see a link to the code and schematic which are both quite similar (an extension) of this one.
please tell how to make this synth. i was looking for in your page but I can't find it

Hola! Muy bien APENA vi tu Proyecto Una pregunta se puede simular un sonido diesel al mismo tiempo simulando un control de Velocidad?

good scope sync! Made for a very interesting visual display. For a moment there I thought I was tripping :)

nice work! can you give me the code for that, original or altered version is fine with me. I want to play with that!

Jesus, I had no idea the arduino was capable of such noise generation! What isthis R2R network you speak of?

So you've got a 16-bit audio synth? That's excellent news, I might just have to play with that...
teabagtime 4 years ago
why 16?
you have 6 pins on PORTD, 6 pins on PORTB and 6 pins on PORTC = 18 digital i/o pins.
but... there will be speed issues (probably / maybe)

also, nice name!

WOW NICE, noise hmmmmm :D Why not use a simple DAC8080? 8bit ic?

You can get i anywhere i guess... Its just a 8bit R2R IC :)
Ow btw, any chance you put the code online of this demo? I would love to try it out!
