I'm looking for a simple way to generate audio frequencies with an AtTiny85, so it plays an continuous sound (e.g. at 440hz) when an digital Input is pulled to ground. I found an frequency generation sketch in the playground that is described as simple, it also works on an AtTiny but seems to consis…
