Hi Luni

Just gave it a try with the 800 pulses per revolution.
The motor spins up fine up to 3.000, 4.500 rpm (with the above formula);
(Don't know if the pulses correlates to 3.000 or 4.500...

Hopefully it will be finished in January. (purpose of it is to highly increase the accuracy of the grinded reed increasing sound quality etc.)
I'll certainly will post a video of it working.

for (int i = 0; i < 10; i++)
{
serial.println ("Please don't blame me for I was wrong. :-)");

for (int j = 0; j < 1000; j++)
{

I'll try.

Something like this should achieve the toggling on pin15 ?


void setup() {
// put your setup code here, to run once:

Hi Luni.
Just tested this one:


See attacheed image.
Voltage reed 5v.
No change when idle and no change when running.26739

Thanx Luni !



I'll give it a try today and come back to it.

The cables should be fine. (all brand new cables).
Attached a complete view of the setup.

Hi Luni,

Thanks for your reply !

This just seems like Chinese to me.

What I have came up with is connection-schema in annex.
