A friend of mine is blind and I am interested in building a talking meter, now there are various sketches.
One is great at talking and terrible on accuracy, the other is great with an lcd and doesn't talk dated 2016.
After much Tinkering I have hit a problem other than outdated code issues now fixed.
The main code becomes irratic if added to and through ignorance I don't understand why a several sections prior LCD screams about modification and cryptic errors. It seems modification of code throws Bounce.h errors
So I hit apon creating a library file that calls the SD card and enabling it in main code.
The SD card code is an example code that checks card present and serial prints.
The issue is Card.h shows in IDE, the code is ide own template that works standalone.
But the very file I can see in IDE-IDE claims doesn't exist as is the help page link which is dead.
https://docs.arduino.cc/hacking/software/Library Tutorial Page not found
Any suggestions or a tutorial link as stumped
Thanks
