Reading an RC Receiver

Using Arduino Sensors
1

Hi Ive been reading through the forums and looking for a library which I can use to read the output of an rc receiver. All the code in the forums are based on using a composite ppm output. Any help would be greatly appreciated.

Cheers,

Sorry one more thing to add, I would like to be able to read an idividual channel.

If you're only interested in a single channel, then "pulseIn" might do the trick.
Search around the forum for PPM decode.

Thanks AWOL, :slight_smile:
So something like this would work?

unsigned long pulseWidth = 0;
void setup()
{
  Serial.begin(57600);
  pinMode(8, INPUT);
  
}

void loop()
{
  pulseWidth = pulseIn(8, HIGH);
  Serial.println(convert(pulseWidth), DEC);
  
}

long convert(long pulseWidth)
{
  int value = pulseWidth - 1000;
  return constrain(map(value / 5, 0, 200, 0, 180), 0, 180);
}

That looks like a good start - why not try it?
