How it works

This tool transforms standard delay() calls into non-blocking millis() timing logic.

It injects unsigned long currentMillis = millis(); at the start of your loop.
It replaces delay(N); with an if condition.
This allows your Arduino to perform other tasks while waiting for time to pass.

Note: Always review the generated code. You may need to manually rename previousMillis variables if you have multiple distinct delays.
