====== Itof() ======

''Itof()'' (Off Delay Timer) returns false after a specified time has elapsed since the condition turned OFF.

{{:en-us_commands:reference:itof.svg?900|Itof command operation flow}}

''bool Itof(uint8_t timer_id, bool state, unsigned long delayTime)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''Itof(timer_id, state, delayTime)'' | ''uint8_t timer_id'' — Timer number. Supports ''0'' ~ ''255''\\ ''bool state'' — Timer input state\\ ''unsigned long delayTime'' — Preset time in ms | ''bool'' | (Off Delay Timer) returns false after a specified time has elapsed since the condition turned OFF. |


===== Example =====

This example selects MPINO-8A4R(T)-S and uses input ''P0'' and output ''P32''. Call the command on every pass through ''loop()'' without blocking it. The output stays on for 2 s after the input goes off.

<code cpp>
const uint8_t INPUT_PIN = 0;
const uint8_t OUTPUT_PIN = 32;

void setup() {}

void loop() {
  const bool inputOn = digitalRead(INPUT_PIN) == HIGH;
  const bool outputOn = Itof(0, inputOn, 2000);  // Keep returning true for 2 s after the input turns off.
  digitalWrite(OUTPUT_PIN, outputOn ? HIGH : LOW);
}
</code>

===== Precautions =====

  * Call the timer command repeatedly in ''loop()'' so elapsed time and OFF input are processed.
  * Do not share a ''timer_id'' between different timer operations; use a separate ID for each.
