I recently found a project for the attiny85, it is a tap tempo that is basically to measure an average of times between pulses of a switch, well the code that I found is very explained and detailed only that when compiling I get errors, I hope that can you help since I’m not good at this
-I attach the code and the link of the page from where I obtained for more information

Gotta post the error, my man.
I advice you to go to your Arduino IDE, go to File->Preferences, and change compiler warning to all.
When the IDE gives you error, copy ALL the error, and paste it with code tags (Top right of reply window, this icon: </>)

Excuse me, I am new to this forum, I did not understand you correctly, but here I leave the error copied as you said

Excuse me, I am new to this forum, I did not understand you correctly, but here I leave the error copied as you said
It's fine.
I ran through the code a bit, and found out the code is missing declaration of 'updateDTime' for some reason, as indicted by the error log:
EchoWreck:247:5: error: 'updateDTime' was not declared in this scope
updateDTime = 1;
^~~~~~~~~~~
So you can add that somewhere in global ( the part before void setup() ).
uint8_t updateDTime = 0;
The second error is indicated here by the error log:
expected '(' before 'updateDTime'
This line, for some reason, doesn't have brackets:
if updateDTime {
updatePWM();
}
So you can add the brackets, and it should compile
if (updateDTime) {
updatePWM();
}

compiled !!!! Thank you very much for the help
