Hello again.

I hope, I do not disturb too much with my noob questions.

I had a device which can read Secondary Ignition Voltage and displays RPM.

And it was very useful. It was hand held device and do not support for serial output. So I want to build this thing based on arduino to send this data to pc.

Is there any suggestion for sensors.

My Humble Regards.

If you go forward with this, please keep us informed this is interesting

I'm trying o forward. And it was hard. Due to lack of electronic knowladge plus, finding parts in my country slow down my effort. And I will not surrender.

Anyhow.

I found, that inductive clamp (which used for chineese ignition advance light) may useful. And I need voltage divider too.
