Good day,
I am currently attempting to modulate a random function based on noise. I am working on a MKR Zero and a separate noise generator. However, I am encountering an issue: the noise generator has an input/output of 12 V, whereas the Arduino only takes 5 V. I want to keep those oscillations, so I can't really use a step-down module. What's the best way to tone it down so I can use the generated noise on the analog pin?
I am also a beginner at the moment and have just started working with the Arduino for the first time.
Thanks
Use a voltage vivider
Thank you very much. I will look into it. Does this method not remove the frequency on which the random numbers are based?
It only affects the amplitude of the signal.
The resistors of course will add additional random noise but a minuscule amount
You should use 1% resistors. R1 =7.15K, R2=4.99K
