Hi everyone,

I’m working on the ultrasonic sensors coming from the nexus robot 4WD and I don’t receive any data.
Thanks to the library given with it, I could write a simple code for one sensor:

SONAR sonar11(0x11),sonar12(0x12),sonar13(0x13),sonar14(0x14);

void setup()
{
SONAR::init();
}

void loop()
{
sonar12.trigger();
delay(SONAR::duration);
Serial.println(sonar12.getDist(),DEC);
sonar12.showDat();
delay(500);
}

The only reply I have is this one:
Uª Uª 65535

Could you help me? Thank you very much!

Some of the examples in the manufacturer’s manual has a different line for the SONAR::init() line and do:

SONAR::init(13);

Can you try that?

Hi,

I already tried this and it didn’t work too :frowning:
Thanks anyway :slight_smile:
