Detection of Tics for a time watch machine

[Barbess]

Hello everyone,
I am a novice trying to design a time watch machine using ESP32, and I am having problems being able to detect tics. You can see on the attached picture, my approach for detecting tics. First, we look for a value between 5 and 0, this value marks the beginning and the end of a tic. So (1) we look for 5>value>0, once found, we initialize the variables. (2) we have to detect the growth of the values, the values grow until a peak, (3) we find this peak and take the time, once found, (4) we have to detect the decrease of the values, and to be sure that they are decreasing we have to (5) search for 5>value>3 once found, we initialize the variables, we count and detect the growth of the values, and the cycle starts again until count = 6. The conditions are independent of each other, for (2) to be executed, (1) must be done, for (3) to be executed, (2) must be done, for (4) to be executed, (3) must be done, for (5) to be executed, (4) must be done.

Here you can see what I have written as code, but which obviously doesn't behave as I want, because I can't make the conditions independent of each other and I can't do the detection of the increase and decrease of the values. Can anyone suggest a solution to my problem? Thanks in advance

  {
    minValue = value;
