What is the best way to blink an led multiple times

[Paul Woodard]

I have a temperature measuring setup (who doesn't) but it is in a box and I want an LED to flash when it takes a reading. Here are the two flows I came up with, but I wonder which is 'better' or if there is even a 'better' solution.

Note, the two gpio pins just go to an LED with both green and amber and I wanted to see which looked better.

I like the second... could be simplified slightly :-)

I tried a more JavaScript approach using setTimeout and setInterval to send the triggers.

// trigger frequency

var trigger = setInterval(function(){

    node.send(msg);

}, 500);

// trigger total time

setTimeout(function(){

    clearInterval(trigger);

},2000);

return null;

Ohhh I didn’t know you could send the same message multiple times!! And this is simpler. I learn something new every day :>)

I love this forum, what great help! Two great ‘better’ solutions!
