here's what my output is

[Reply #16 on:]

I'm confused about what the device is, still. As in, its part number.

You don't generally connect things via a single wire. Does the device have a ground wire? Is it wired to the Arduino ground?

i don't have a photo or a schematic sir,

Do you have a phone with a camera in it? How about using it?

here's what my output is

I believe you. You don't have to attach a screenshot. You can copy and paste from the output window.

here's what the device is... i bet it is just newly constructed so got no full ideas about it.

but i will try all your suggestions now sir...thanks a lot. u guys got my sincere gratitudes

Code:

  pinMode(forwardPin, INPUT);
  digitalWrite(forwardPin, HIGH); // Turn on the pullup resistor.

so the new code will be like this?

Code:

int forwardPin = 12;

void setup()
{
  Serial.begin(9600);
  pinMode(forwardPin, INPUT);
  digitalWrite(forwardPin, HIGH);
}

void loop()
{
  int forwardState = digitalRead(forwardPin);
  if (forwardState == HIGH)
  {
    Serial.println("HIGH");
    delay(1000);
  }
  else
  {
    Serial.println("LOW");
    delay(1000);
  }
}

Why not try it and tell us?

[Reply #21 on:]

With those 1 second delays you're not going to read more than the fact a signal was sent from the remote and that only by luck.

Try keeping track of what state the pin was last time it was read and only printing when the state changed. Then take the delays out. But fix the wiring first.

Code:

  pinMode(forwardPin, INPUT);
  digitalWrite(forwardPin, HIGH); // Turn on the pullup resistor.

will it also work if i make it a pull down resistor? some like...

Code:

pinMode(forwardPin, INPUT);
  digitalWrite(forwardPin, LOW); // Turn on the pulldown resistor

[Reply #23 on:]

No, there are no built in pulldowns

[Reply #24 on:]

No, there are no built in pulldowns

thanks sir that helped a lot ^^

Code:

pinMode(forwardPin, INPUT);
digitalWrite(forwardPin, LOW);   // turn off the pull-up resistor

All that second line does is turn off the pull-up. There had to be a way of doing it, and this is it.

oh really sir?! gee thanks! i will try it now

[Reply #27 on:]

Do you know how to wire a pull-down resistor?

yes sir i read about it

I'm really not used to someone calling me sir check my profile. Just call me Habib
