for the time to be displayed more accurate you have to use the dtostrf() function which converts the float/double to a string iirc

[ipadize]

you can also write this: ") + (duration));

that makes it a little more tidy

Very nice and very useful. Thanks for sharing.

Tres bien! You are very good at explaining a principle very clearly. Thank you.

Thank you for explaining this function. I have got an encoder signal from a slow running motor, and I guess a way could be to measure the time between pulses using this micros function. I guess some hardware counter is used and you read that counter by micros. I looked in the hardware description for ATmega328P, but could not identify this counter. Do you know the name of this counter?
