Jul 31, 2025 Added the following notes.
- After calling tone() and noTone(), the digital output by digitalWrite() may not be controlled properly for the pins specified by these functions.
- When tone() is called with a specific pin, the frequency of the square wave that was previously output by tone() from another pin is not correctly maintained.
