Any Arduino geeks here? Have a question..
So, I want to build a sine wave display for my oxygen sensor signal. Highest refresh rate available, flowing from right to left if possible.
Where do I start? |

Doesn't Sine Wave read vibration frequency?

cannot help you other than to say that the O2 signal output is generally quite digital in nature. It slams between two voltages when hot and sensing lean/rich. Wideband O2 sensors will give a more linear response.

Re: Any Arduino geeks here? Have a question..
I've scoped o2 sensors with a few different pieces of equipment. While it is pretty fast between hi and lo, you can see a curve to it if you have high enough resolution.
My fiance is a bigger computers / electronics nerd than I am, so when the knuckle-dragger stuff is done the two of us will have fun with this project. I'll post results... |
