I have a project that records interrupts from a reed switch to nodemcu.

It records like this: 0.3,0.6,0.9,1.2 Then what I want to happen is to go back to zero when it successfully HTTP.POST to a webserver.

How can I do it? Thanks!

volatile float rainrate = 0.3;
volatile float total;

void count {
  total += rainrate;
}

  • So how do you set a variable to zero? – romkey Jan 23 at 20:09
  • are micros() effective for this? – Giddsec Jan 24 at 4:38
  • You are missing a lot of context on this question. Can you post the entire program? – Eugenio Pace Jan 24 at 5:23
  • Yea sorry, got it working already, after HTTP.POST, I put total = 0; – Giddsec Jan 24 at 5:58

Try putting your total variable to 0, like this: total = 0; It should work like this.
