Hello Dear Node Red users,

I need again your help, I'm trining to figure it out since yesterday without any luck (no code writing experience).

I want to send a time stamp to a node, each second, the output should toggle, the timestamp should be once diverted to Output 1, second time to Output 2, and than again to Output 1.

I share with you what I want to achive. Maybe there is a even more neater solution.

I want to use a 8x32 Led Martix with Wled to display a stationary clock with blinking dots.  
As default Wled can only display HH:MM:SS in a scrolling form. I don't need the seconds, don't want to have the time scrolling.

The only solution which I have found, is to send the time in text format to WLED, once with dots 23:12, once without 23 12. In this way the dots are blinking and I know that my server is allive. I'm using a really dirty solution whith 2 gates which are toggled alternativelly. The problem is by interupting this flow, both gates will toggle in the same status. I would need to interlock them somehow, but have no ideea.

Help is apreciated.

Have a great evening,
