Signal intermittently sent twice

[Goofyeet]

Sometimes, the signal will be sent twice.

The second signal usually starts between 50-95ms after the first signal has finished. I can recreate the issue by purposefully double clicking the buttons fast. I can also get rid of the issue by activating the push button with a sharp and quick press. However, under normal use, a second signal will be intermittently sent.

This could be due to there being no debounce delay in the code.
