How to read interal sensor values (Me Auriga)

#1

Hi everyone,

I’m trying to figure out how to read values from MeAuriga internal sensors:

Gyroscope
Sound sensor
Passive buzzer
Temperature sensor
12 PXL LED RGB panel with light intensity sensor

Is there a guide on how to get values from this sensor?

Many thanks in advance,

Diego

Hi braghettos,

You can read value from Gyroscope, Sound sensor,Temperature sensor,light intensity sensor.
But the Buzzer and the LED RGB are not sensors, they can’t detect anything and output a value.

You can program these parts on Auriga with mBlock software:

Here is a simple example to read the value from light sensor 1:

Here is a mBlock program online course for Ranger to you for reference.

Hi tec support,

I’m writing directly the code on Arduino IDE instead of mBlock, are there any code examples on how to read these values from MeAuriga?

Thanks again,

Diego

There is example program to use these sensors with Arduino, but you may refer to the Arduino source code of the firmware for Auriga have a try.

I am unable to find an example of light sensor.

For gyroscope sensor,

MeGyro gyro(1,0x69); //On Board external gyro sensor

For the others:

case  LIGHT_SENSOR:
case  SOUND_SENSOR:
        case  POTENTIONMETER:
          {
            if(generalDevice.getPort() != port)
            {
              generalDevice.reset(port);
              pinMode(generalDevice.pin2(),INPUT);
            }
            value = generalDevice.aRead2();
            sendFloat(value);
          }
          break;
        case  TEMPERATURE_SENSOR_1:
          {
            if(generalDevice.getPort() != port)
            {
              generalDevice.reset(port);
              pinMode(generalDevice.pin2(),INPUT);
            }
            value = calculate_temp(generalDevice.aRead2());
            sendFloat(value);
          }
          break;

What is generalDevice?

Hi braghettos,

For the Arduino source code, we may don’t have enough ability to explain the details for users.
Here is commentary link for Makeblock library, you may check if you can find the explanation there.

Another suggestion is that you may refer to the automatically generated arduino code when you program with mBlock software.
