''IbounceOn()'' applies the time filter only when the input changes from OFF to ON.

{{:en-us_commands:reference:ibounceon.svg?900|IbounceOn command operation flow}}

''bool IbounceOn(uint8_t pin, uint32_t debounceTime)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''IbounceOn(pin, debounceTime)'' | ''uint8_t pin'' — Input pin number\\ ''uint32_t debounceTime'' — Stable-state confirmation time (ms) | ''bool'' | Applies the time filter only when the input changes from OFF to ON. |


===== Example =====

<code cpp>
const uint8_t START_INPUT = 0;
const uint8_t STOP_INPUT = 1;
const uint8_t RUN_OUTPUT = 32;

void setup() {
  Serial.begin(115200);
}

void loop() {
  const bool start = IbounceOn(START_INPUT, 100);  // Apply the time filter only when the input changes from OFF to ON.
  const bool stop = IbounceOff(STOP_INPUT, 100);  // Apply the time filter only when the input changes from ON to OFF.
  const bool run = start && !stop;
  digitalWrite(RUN_OUTPUT, run ? HIGH : LOW);

  static bool previousRun = false;
  if (run != previousRun) {
    previousRun = run;
    Serial.println(run ? F("motor RUN") : F("motor STOP"));
  }
}

===== Precautions =====

The ''Ibounce'' functions retain state, so keep calling them in ''loop()''. Specify the actual pin or logical channel for your product.
