This is my effort at a node which could be handy for people who like flashy things on their dashboard.
You want to make a light blink rather than just be constantly on.
Though not complicated, this may save you some heart ache.
The toggle node does this for you and you can configure it with 3 settings:
1 - how fast you want it to toggle. (Set in milliseconds)
2 - The first message to be sent
3 - The second message to be sent
There is an optional offmsg which could be handy if you are blinking a light between two colours and want it off when the flashing has stopped.
Example flow included.
