I am brand new to Node-Red but I am trying to make or find a simple timer. I know there are a few things like bigtimer but they all seem to be based of times of day and such.
I just want a timer that I can type in a number and press "start". It will then run for the number of minutes entered and then stop. (this is for a raspberry pi so a simple output of 1 and 0)
It should also be able to stop at any point if a "stop" button is pressed.
Bonus would be if there was a visual. At the very least, a countdown visible on the dashboard, better if there was like the doughnut graph going from full to 0.
Can anyone point me in the right direction?
