Is this simplified flowchart describe my code?

Hi Imane

Firstly, it's not a good idea to have two threads running on the same topic .. likely the Mods will want to modify that .. .

Have I got this right ? You're trying to build a circuit to emit a dummy pulse to test your pulsemeter ?

What have you done so far ? Built the circuit ? Tried but failed ?

You have made a historical invention. A decision point that has one "no" branch and two "Yes" branches. In this specific case, the "Yes" branch would do one chore and then the other:


A conventional approach is to have just two exits: "Yes" and "No". If the "Yes" branch can split again you would have a second test but you don't here.

In the "Yes" branch you would perform the two "Yes" tasks sequentially when using a single core processor.

1. Display the PPG signal in the plotter, and then
2. The LEDs will light up with the heartbeat

Or execute in reverse.
