EXAMPLE

To test EspPlcTimer2 you can use this small program:

#include "EspPlcTimers2.h"

espPlcTimer t1(TON, 20000); //TON timer, 20s
espPlcTimer t2(TOFF); // TOFF timer, 10s

void setup() {

  TIMERHANDLER; //Call to TimerHandler function

  Serial.begin(115200);
  pinMode(GPIO_NUM_13, INPUT_PULLUP); //input for the TON timer (green)
  pinMode(GPIO_NUM_12, INPUT_PULLUP); //input for the TOFF timer (blue)
  pinMode(LED_BUILTIN, OUTPUT); //output for the TON timer
  pinMode(GPIO_NUM_15, OUTPUT); //output for the TOFF timer
};

void loop() {
  t1.tin(!digitalRead(GPIO_NUM_13));
  digitalWrite(LED_BUILTIN, t1.q());
  t2.tin(!digitalRead(GPIO_NUM_12));
  digitalWrite(GPIO_NUM_15, t2.q());
  if (t1.tin() || t1.q()) {
    Serial.print("T1: ");
    Serial.println(t1.et());
  }
  if (t2.tin() || t2.q()) {
    Serial.print("T2: ");
    Serial.println(t2.et());
  }
};

It's easy to check using Wokwi. Just add the follow circuit:

This is the diagram.json of the circuit. You can upload to Wokwi:

In the Wokwi editor dont't forget to load the EspPlcTimer2 library and the ListLib library:
