EnableOutputCompareInterrupt is only called for duration > 0. This makes it impossible to make a continuous (duration = -1) tone with the tiny core. Attached file works, tested on ATTINY85-20PU with ...

ToneDynamic: An extended version of Arduino tone() function that allows dynamic frequency and duty cycle control. Fully asynchronous and non-blocking. Speaker: A audio class that allows volume control ...

This tutorial will show you how to use the Arduino to play your most-loved tunes. The steps are pretty simple to follow and should get your project running within minutes. The Arduino here creates ...

The project involves coding the Arduino while sequencing 8 tone slots and the frequency of each slot would be controlled by a frequency knob. The controls on this console include four potentiometers ...
