    You Reply: Could you give me your library RTClib. I used the RTClib from this https://github.com/adafruit/RTClib. I'm not sure it‘s the same.

    I uploaded your code in my Rainbow LED. There are only 2 LEDs turning on, not 4.

    And I have another question. I don't understand you how to display minute and how to display hours.
  • Topic: Romeo V2 Voltage issue.
    You Reply: You can try to test motor voltage to GND?not motor + to motor - , that voltage should be close to 8V.
    :)
  • Topic: Romeo V2 Voltage issue.
    You Reply: Do you mean that the battery supply Romeo with 8V and Romeo doesn't connect to DC motor, however, M1 output is 6.1V?

    You Reply: Which DC motor did you use?

    I have tried the above motor. The measurement of the DC motor voltage is 6.1V.  The series of DC moter rated voltage is 6V for fear being damaged. And Writing 255 is the full speed.

    I hope it'll help you!  :)

    I have a couple of test codes. You can have a try.

    Sender:
    void setup()
    {
      Serial.begin(9600);
    }
    void loop()
    {
      Serial.print("wireless");
      Serial.println();
      delay(500);
    }

    Receiver:
    void setup()
    {
      Serial1.begin(9600);
    }
    void loop()
    {
      if(Serial1.available()){
      Serial.write(Serial1.read());
      }
    }
